Mario-style platformer · step-5-preview

Phaser 3 (UMD build). I'll build a platformer with generated textures via Phaser Graphics.

Let me write the index.html with:
- Preload: generate textures using graphics (create textures via Graphics generateTexture)
- Scene: game
- HTML overlays for HUD/controls/win/lose states, or in-canvas text. I'll use DOM overlay styled divs for HUD and messages, and also canvas text. Let me use DOM for controls display and messages — simpler and reliable.

Design level:
- World bounds 200x? Let's do level width ~4200, height 720? Canvas 960x540.
- Ground segments with gaps, floating platforms, coins, enemies (goomba-like patrolling), goal flag.
- Player: generated texture — a small Mario-like character drawn with graphics (rects) as texture, plus flipX for direction.

Physics: arcade with gravity 900, player velocity, collide world bounds false (death by gap fall).

Stomp detection: check if player.body.velocity.y > 0 and player bottom near enemy top. Use overlap with callback checking body.blocked/touching.

Let's write carefully.

Key implementation details:

Textures generated in a "Boot"/preload scene using make.graphics:
- 'player' 24x32 graphics: red hat, skin face, brown/blue body... draw Mario-ish pixel art via filled rects.
- 'enemy' 24x24: brown goomba with feet.
- 'coin' 16x16: yellow circle with darker outline.
- 'brick'/'ground' tile 32x32.
- 'flag' 32x64.
- 'platform' 32x16? Use a single 'plat' texture 32x32 tileable for the stone platforms.

Level layout data:
Ground segments: [ [0, 620, 600], [660,620,300], ... ] Actually ground top at y=620, height to bottom of world 700.

Let me define level in a compact way:

tiles of 32. Ground segments (x start, width in px):
seg1: 0..576 (18 tiles) — with enemy patrolling on it.
gap 64 (576..640)
seg2: 640..960
gap 80 (960..1040)
seg3: 1040..1312
Then floating platforms above.

Floating platforms at y=480, 400, 320 etc.

Coins above platforms and over gaps.

Enemies: placed on ground segments and platforms, patrolling within set bounds; turn at ledge (check tile ahead) — simpler: patrol between two x values.

Goal flag near end at x ~ 4000 on final ground.

World height 720, canvas 960x540; camera bounds set.

Death: fall below world height → lose. Also side contact with enemy → lose (player becomes dead → show lose overlay).

Also allow restart with R key and Restart button.

Score/HUD: coins collected, and maybe time. Keep it: coins collected/total, and a message.

Let me write the code.

Player physics:
- body.setSize(16, 30) with offset to match texture; texture 24x36.
- gravity y = 1200, jump velocity -520, move speed 200, acceleration... use direct velocity set: if left/right → ±220 with accel 1500 and drag 1200. Simpler: setVelocityX directly.

Prevent double jump: track canJump = body.blocked.down || body.touching.down (onFloor). Use player.body.onFloor().

Stomp: in overlap callback, if player.body.velocity.y > 0 && player.y < enemy.y - 4 → kill enemy, bounce player (-380), small particle/scale tween. Else → die.

Also add invulnerability? Not needed; die immediately on side contact.

Win: overlap flag → show win overlay, freeze physics (player.setVelocityX(0), disable input or set velocity 0 via body.setAllowGravity(false)).

Camera: startFollow with lerp 0.1, setBounds.

Background: draw gradient sky with graphics, plus hills and clouds (generated textures or graphics drawn once in a static group). Use graphics with parallax via scrollFactor.

Let me draw sky as a rectangle using graphics scrollFactor 0, and clouds via generated texture 'cloud' with tileSprite? Simpler: draw clouds as images in a group with scrollFactor 0.3.

Now write the file. Also DOM overlay for controls at top-left, coin count top-right, and centered message panels for win/lose with Restart button.

I'll do HUD in DOM (absolute positioned over canvas container), which is clean and lets me use CSS.

Let me write it.

Details on generated textures: In preload, create with this.make.graphics({x:0,y:0,add:false}) then generateTexture(key,w,h), then destroy.

Careful: this.add isn't available in preload for scenes? this.make.graphics works fine in preload/create. I'll do it in create() of a Boot scene or just at the start of create() in main scene. Actually generateTexture in create is fine.

Text: use this.add.text for some labels? DOM is enough.

Let me write level data now:

const LEVEL = {
  width: 4400, height: 720,
  groundTop: 620,
  groundSegments: [
    {x:0, w:576},          // start area
    {x:640, w:320},        // 640-960
    {x:1040, w:288},       // 1040-1328
    {x:1408, w:256},       // 1408-1664
    {x:1744, w:352},       // 1744-2096
    {x:2176, w:288},       // 2176-2464
    {x:2544, w:448},       // 2544-2992
    {x:3072, w:416},       // 3072-3488
    {x:3568, w:832},       // 3568-4400  final with flag at 4150
  ],
  platforms: [ // x,y,w (h=32) small blocks, y is top
    {x:300, y:470, w:128},
    {x:480, y:360, w:128},
    {x:700, y:440, w:96},
    {x:1100, y:470, w:128},
    {x:1450, y:440, w:128},
    {x:1500, y:330, w:96},
    {x:1800, y:450, w:160},
    {x:2050, y:350, w:96},
    {x:2260, y:440, w:128},
    {x:2620, y:470, w:128},
    {x:2900, y:370, w:160},
    {x:3150, y:460, w:128},
    {x:3400, y:350, w:128},
    {x:3700, y:450, w:160},
    {x:3960, y:340, w:128},
  ],
  coins: generated // places
  enemies: generated
}

I'll compute coins programmatically: above platforms and above ground, plus some over gaps.

Enemies: on ground segments, patrol around a center with a range; also one on a wide platform.

Number coins ~ 20.

Let me place coins explicitly in arrays for control. I'll generate: for each platform, coin row above (x+16..w step 32). And on ground, a few clusters. Fine.

Enemies list: {x, y, minX, maxX}.

Enemy y = groundTop (y of top of ground) with texture height 24, so y = 620 - 24 = 596. For platform with height 32: y = platY - 24.

Flag: at x=4250, base on ground top 620, texture 32x96 → y = 620-96 = 524.

Player start: x=80, y=560.

Now write the code carefully.

Physics groups: platforms = this.physics.add.staticGroup for ground and floating platforms? Ground segments could be static images; use staticGroup with image 32x32 tiles scaled? Use this.add.rectangle? For arcade collisions, need physics bodies. Use staticGroup and add multiple 32x32 images via multiple calls, or create one image per segment and use setDisplaySize? Scaling a 32x32 texture to a 576x100 rect would stretch the texture — for brick pattern it looks stretched. Better: tileSprite with static body? For static physics body created from image, use `plat = platforms.create(x, y, 'block')` then `plat.setScale(...)`. Static body scaling works in Phaser 3 (refreshBody needed after scale). But texture stretching for bricks — I'll make a 'ground' texture 32x32 with brick/soil pattern, and one tile per 32px for ground segments (18 for 576). That's fine, and gaps come naturally.

Total tiles: ~576+320+288+256+352+288+448+416+832 = 3776 px /32 = 118 tiles plus platforms ~15*4=60 tiles. ~180 images, fine.

Platform tiles: use a 'stone' texture for floating platforms (grass-top stone block). Make ground tiles distinct (brown soil with grass top? Grass top only on top row). I'll use: top row tile 'grass' (grass + dirt), and below 'dirt'. Nice look.

Now camera follow + bounds.

Also handle keyboard: cursors + A/D + Space (also W / Up for jump). Prevent Space page scroll: preventDefault on capture.

Let's write.

For text/HUD in DOM:

<div id="hud"> coins: <span id="coins">0</span>/<span id="total"></span> </div>
<div id="controls"> ← → / A D: Move  Space: Jump  R: Restart</div>
<div id="overlay" class="hidden"> title, message, button Restart </div>

Overlay pointer-events auto.

Now code. Also add small dust particles on landing? Keep simple: skip particles, maybe a tween scale for coin collect "+1" text floating. Nice touch, use simple text tween.

Let me write index.html now.

Also need the "visible coins" reset — restart resets everything.

I'll implement scene restart via this.scene.restart() — simplest and resets everything. Careful: generated textures in create are fine to regenerate (or guard). I'll generate textures in a separate Boot scene that runs once, or generate in create of main scene each time (key collision warning but works). Better: do texture gen in preload of the main scene via a function that checks if texture exists (this.textures.exists(key)).

Let me write it.

Player texture drawing (24x36):
- hat: red rect x=3,y=0,w=18,h=6; brim x=2,y=5,w=20,h=3
- face skin: x=5,y=6,w=14,h=8
- eye: dark pixel at x=15,y=8,2x2
- mustache: brown x=7,y=12,w=10,h=2
- shirt/overalls: blue x=4,y=15,w=16,h=9; red shirt sleeves x=2..22 y=15 h=5
- arms skin: x=1,y=17,3,7 and x=20,y=17
- shoes: brown x=2,y=28,w=8,h=7 and x=14,y=28

Let me be careful with heights: total 36 tall; y from 15 to 28 body, shoes 28-36. OK.

Enemy 'goomba' 24x24: brown body rounded-ish rect x=2,y=4,w=20,h=14; feet dark x=1,y=18,w=8,h=5 and x=15,y=18; eyes white x=5,y=8 4x5 and x=15; pupils black; angry brows.

Coin 16x16: gold circle radius 7 fill 0xFFD700 with darker ring, inner shine.

Flag: pole gray rect x=14,y=8,w=4,h=88 (texture 32x96) and triangle flag green x=4,y=12,w=12,h=16. Actually flag base: on ground.

Let me code the pole so it's clearly visible.

Now write the file.

For enemy patrol, in update: enemy.setVelocityX(dir*speed); if enemy.x <= minX → dir=1; if >= maxX → dir=-1; setFlipX(dir<0).

Also enemies should turn at ledges: check using a simple ground probe: compute tile below ahead? Simpler to use minX/maxX bounds. Fine.

Collisions: physics.add.collider(player, platformsGroup); collider(enemies, platformsGroup).

Note: ground tiles as static images in a static group works.

Fall out of world: in update, if player.y > 700 → die (or set collider with world bounds bottom false → falls). Use check.

Write code.

Overlay hidden class.

Also "Display the controls" — done in DOM + maybe in canvas text. Good.

Let me now write the full file.

Now run it in the browser. Let me check the browser tool availability.

Note: pixelArt: true with scale FIT is fine. But pixelArt makes textures nearest — fine.

Issue: player texture is 24x36 drawn with pixel art; body size 15x32 offset (4,4) — the player's drawn feet are at bottom 36 so offset 4 leaves 32 height from y=4 to 36. Good.

Enemy texture 24x22; body size 22x20 with default offset (0,0)? I used setSize(22,20) which sets offset to (0,0)... Actually setSize(w,h,center) - default center=true, which centers the body in the texture: offset = ((24-22)/2=1, (22-20)/2=1). That's fine.

Flag: sprite 60x100 texture, body setSize(20,90) centers → offset (20,5). The flag pole is at x 13-19 within texture. Body center of texture at x=30... so the body is not aligned with the pole. Better to set offset manually so the body overlaps the pole. Let's set body.setSize(12, 88) and setOffset(FLAG_X-?). Hmm, sprite origin default is center (30,50) of 60x100 texture, so sprite.x = center. Pole occupies x 13..19 → relative to center 30: -17..-11. So the body should be at x from -17 to -11 (6 wide) relative to sprite.x. With arcade body, body position = sprite.x - textureDisplayOrigin... For a body of width w with offset ox, the body spans [x - displayOriginX + ox, ...+w] where displayOriginX = 30 - 0 = 30 (since origin .5 of 60). Actually for sprite, body offset is relative to texture top-left, and body position = sprite.x - originX*width + offset. So body left = sprite.x - 30 + offset.x. We want left = sprite.x - 17 → offset.x = 13. And vertically: top of pole at y=6 in texture → sprite.y - 50 + offset.y = sprite.y - 44 → offset.y = 6, height 88.

So setSize(8, 88) and setOffset(13, 6). Also I placed the flag sprite at y = GROUND_TOP - 50 with texture height 100, so sprite top = 570-100=... GROUND_TOP=620, sprite.y=570, top=520, bottom=620 (base at ground). Good. The base block at y 92..98 in texture → 612..620. Good.

Let me change the flag body.

Also: coin overlap with static group — coin body from staticGroup create with 'coin' 16x16, body is full tile 16x16. Fine.

Coins at [760,570] and [792,570]: those are near start area ground at 576..640 gap? 760 is on seg 640-960 ground, y=570 which is 50 above ground top 620 — reachable by jump (jump velocity -560, gravity 1250 → height = 560²/(2*1250) = 125px). OK.

Coin [4100,570], [4140,570] ground on final segment. Fine.

Enemy at 3700 with onPlat: y=450-24=426, patrol left 3580 right 3700 — that only covers the left part of the platform at x 3680..3840. Fine-ish. Actually platform 3680 w=160 → 3680 to 3840. Let me set enemy 3700 left 3690 right 3830.

Also enemy at 300: patrol 180..540 — but the first platform at 300,470 is above; enemy on ground. Fine.

Now, the "Level Complete" overlay message for coins total uses coinCount+coinsRemaining. Fine.

Potential problem: `this.hillGroup` unused variable - harmless. Also unused var 'self' in buildGround — harmless.

Another: `this.player.setCollideWorldBounds(false)` — the player can walk beyond level left edge; camera bounds handle. Fine but let's set the world bounds to prevent walking left off-screen: physics world bounds set to (0,0,LEVEL_W,LEVEL_H) and collideWorldBounds(true) would prevent falling out of the level bottom too... but then gap death won't work because player would land on y=LEVEL_H bottom bound. So keep false. But left edge: player could walk to x<0. Minor. Set a min: if player.x < 10, clamp. Actually world bounds collideWorldBounds true would create invisible floor at level bottom = bad. Instead, in update, clamp player.x >= 16. Let me add that.

Also add collideWorldBounds(false) keep.

Also check: when the game restarts, the DOM overlay is hidden and HUD resets via create. Good.

One concern: `this.scene.restart()` re-runs create, regenerating textures skipped, re-adding graphics. Fine.

Another concern: interval polling for scene; simpler to use game.events.on('poststep'). It's fine.

Let me also verify that in `create`, `this.input.keyboard.addKeys('A,D,R,SPACE,W,UP')` works with space name 'SPACE'. Yes.

Note: Space key with Phaser captures? Phaser's keyboard plugin adds a listener on window with preventDefault for captured keys... Actually Phaser 3 by default adds capture for SPACE, preventing page scroll. My extra preventDefault is fine.

Also: pixelArt: true makes canvas rendering use nearest; ok.

Let me fix the flag body, the enemy platform patrol range, and x clamp, then test.

The game loaded and looks great. Coin total 38 matches COIN_SPOTS length (38). Let me verify: COIN_SPOTS count... yes seems 38.

Now test running right, jumping onto platform, camera following. Let me press ArrowRight for a while and then screenshot.

The browser tool "key" action — I can hold a key? It probably presses once. Let me try key with text "ArrowRight" and multiple times, or use "type". Let me check by trying key press and looking at screenshot.

Hmm, the player didn't move — it seems the key press didn't register, or the keydown happened but then... The player is still at x=90. Maybe the browser key action sends a keydown only for one frame (Phaser's key state resets). Let me try dispatching a longer press — maybe use `key` with a hold. The tool likely does keydown+keyup quickly, and Phaser's `isDown` is true during that instant but update may not have run.

Let me instead evaluate JS via inspect to drive the game programmatically? The browser tool has "inspect" action which runs JS? It returns DOM etc. Let me try to simulate input by directly setting player velocity via a script injected... I can't easily inject JS.

Alternative: use `type` action to type text? Or maybe holding the key: try `key` with the same key multiple times in a row and screenshot in between. Movement per frame: velocity 215 px/s; if key lasts ~1 frame (16ms) → ~3.5px. Not visible.

Maybe the browser tool's keydown persists until keyup? The screenshot right after shows no movement, so it's a quick tap.

Let me check whether the inspect action lets me run JS. Let's try action "inspect" with text maybe a JS expression. Risky. Let's test: inspect with text "document.title".

Inspect doesn't run JS. I need another way to drive the game for testing. Options:
1. Add a temporary test hook (auto-pilot) controlled by a URL query param, e.g. `?autopilot=1` that simulates holding right + jumping. That's a reasonable dev aid but could be seen as leftover. I could add a small, harmless debug/test hook that is only active when the URL has `?test=1`. Actually a cleaner approach: use the browser's `key` action but check whether keydown persists. Maybe the tool's key action does keydown without keyup (some harnesses do that). The screenshot after ArrowRight showed no movement, so no.

Let me try `drag`? Not relevant. Maybe `click` on the canvas and then use... no.

Alternative: I can verify physics behavior by simulating keyboard events through the DOM in the page? Can't run JS.

Option: Write a temporary test HTML file that loads phaser + my game code and drives input programmatically... but I can only inspect one page at a time via the browser tool which navigates to index.html presumably. Maybe the browser tool can load a different file? The action "reload" reloads index.html. Perhaps I can pass a URL? Not in the tool schema.

Best approach: add a tiny built-in test hook to index.html that runs only when `location.search` includes `autotest`. That's a common pattern and harmless in the final artifact. Let's do it: when autotest is on, simulate input by pressing keys programmatically via Phaser's keyboard plugin (simulate key down) and log states to console.

Actually simpler: I can implement the autotest by directly setting `this.keys.D.isDown`-like state? Better to use Phaser's keyboard plugin: `this.input.keyboard.addKeys`... Simulating: use `scene.input.keyboard.manager`? Simplest: in the update, if autotest mode, override input with scripted values and log.

Let me implement: in create, if (location.search.indexOf('autotest')>=0) { this.auto = true; } and in update, if (this.auto) read scripted flags `this.aiLeft/right/jump` and log positions periodically. Then, if autotest, run a scripted sequence using timers that log coin count, onFloor, camera scroll, then triggers restart and logs.

Then in the browser, navigate to index.html?autotest=1 — but can I navigate? The browser tool reloads index.html; maybe reload keeps URL. Perhaps I can just use "reload" after editing and then... the URL would be the sandbox's file URL. Hmm, I can't append a query.

Alternative approach without URL: use a numeric key to toggle autopilot, e.g. press "P" to toggle auto-pilot, and "T" to trigger the test sequence. Since the browser tool can send keys, pressing P would work if keydown registers. Earlier the key action seemed not to move the player — but did the key event reach the page? Let's test: press "P" (autopilot toggle) and see if the player starts moving. If the key event reaches the page, autopilot will engage and the player will move continuously — that would also prove that plain key presses just aren't "held".

But wait — my global R handler worked? Unknown.

Let me test whether key events reach the page at all: implement autopilot toggle and check screenshot after pressing P. Good plan; also gives me a way to test camera and stomp.

Actually, even better: make the autopilot a full test sequence that runs automatically when toggled, with console logs I can read via console output.

Let's implement:

In create:
```
this.auto = false;
this.input.keyboard.on('keydown-P', function(){ this.toggleAuto(); }, this);
```
toggleAuto: this.auto = !this.auto; console.log('AUTOTEST', this.auto); if turning on, schedule steps via this.time.delayedCall / time events.

Scripted sequence (all using this.time.line or delayedCall chain):
1. hold right for 1500ms → log x, onFloor, camera scrollX
2. hold right + jump → log jump apex, verify no double jump (record body.y min, and check velocity.y sign changes only once)
3. land on platform at x=300,y=470: approach and jump right onto it → verify y <= 470 (standing)
4. collect a coin → verify coin count 1 and coin removed
5. continue right to enemy at x=300 on ground, jump on it → verify defeated
6. fall in gap → verify GAME OVER
7. press R restart → verify player x back to 90, coin count 0, camera scrollX 0.

That's a lot; let me write a moderate scripted test with console logs, using an input override in update:

```
update: function(){
  var left, right, jump;
  if (this.auto) { left = this.aiLeft; right = this.aiRight; jump = this.aiJump; } else { ... real input }
}
```

And logging helper `this.log(...)` that console.logs with a prefix.

The test sequence via a queue of steps executed in update based on elapsed time in auto mode... Simpler: use this.time.delayedCall with callbacks setting ai* flags.

Let me write it.

Also important: check that the game is completable — my script could also just run a "walk to flag" check. Not needed; I'll spot-check geometry.

Also, I should double-check the coin count total: 38 in HUD, COIN_SPOTS has 38 entries. Let me count via node.

Let me now add the autotest hook code. I'll keep it small and clearly documented as a test hook (only toggled by the P key).

Implementation in update: replace the input block:

```
    var left, right, jump;
    if (this.auto) {
      left = this.aiLeft; right = this.aiRight; jump = this.aiJump;
    } else {
      left = ...; right = ...; jump = ...;
    }
```

Then after that, jump logic same.

Test sequence function:

```
    toggleAuto: function () {
      this.auto = !this.auto;
      console.log('[TEST] autopilot =', this.auto);
      if (this.auto) { this.runTests(); } else { this.aiLeft = this.aiRight = this.aiJump = false; }
    },

    runTests: function () {
      var s = this;
      this.aiLeft = this.aiRight = this.aiJump = false;
      var t = 0;
      function step(label, delay, dur, l, r, j, after) {
        t += delay;
        s.time.delayedCall(t, function () {
          s.aiLeft = !!l; s.aiRight = !!r; s.aiJump = !!j;
          console.log('[TEST] ' + label + ' start (x=' + Math.round(s.player.x) + ', y=' + Math.round(s.player.y) + ', onFloor=' + s.player.body.blocked.down + ')');
          s.time.delayedCall(dur, function () {
            if (after) { after(); }
          });
        });
      }
      ...
    }
```

Careful: if the game restarts (R) during autopilot, delayedCalls are cleared on scene restart. Fine — I'll restart via the same restart() function which uses scene.restart() and then the new scene has auto=false. For the restart test, I'd rather set a flag `this.autoPending` and re-run after restart. Simpler: do the restart test as a separate manual sequence. Let me handle it: after reset, the scene restarts; the new scene's create sets auto=false. To continue the test after restart, I'd set a scene registry flag: `this.registry.set('auto', true)` and in create check it. But then autopilot would keep running forever, which is bad. Let me structure: in create, if registry auto requested, run the post-restart verification and clear the flag.

OK let me write it. Keep it reasonably concise but functional.

Actually, time is limited (15 min budget overall, maybe ~5 min used). Let me be efficient: implement autopilot test with these steps:

Step A: run right 1200ms (pass enemy at x=300? enemy at 300 patrolling left of 300 area... it may kill us). Hmm, the enemy at x=300 with patrol 180..540 will be on the path. For the jump/stomp test, I'll intentionally run into it to verify stomp. Good: run right and jump when near enemy.

Let me design the script:
1. Reset flags.
2. Hold right 900ms → log; by then x ~ 90+ ~200px... At 215px/s, 900ms → x≈285 while enemy at 300 is moving toward us (speed ~55-80 px/s, moving left initially dir=1 → moving right!). enemy.dir=1 initially so moves right toward 300-540. Collision likely → death. Instead: first do jump test in the start area:
   - Step 1: right 400ms (x≈180)
   - Step 2: right+jump 300ms, log apex y, onFloor false; then verify single jump by holding jump for another 600ms and confirming the player does not rise again (max height measured after apex).
3. Then release, release right: stop → land.
4. Then approach enemy at x=300: hold right, wait until player.x > enemy.x - 30, then jump (stomp). I'll implement a polling-based sequence in update instead: if auto and testStage==N do stuff.

That's getting complex. Simpler polling approach with a stage machine in update:

```
if (this.auto) { this.autoUpdate(time, delta); }
```

autoUpdate:
```
var s = this, p = this.player;
switch (this.stage) {
  case 'run': // hold right until x > 200
     this.aiRight = true;
     if (p.x > 200) this.setStage('jumptest');
     break;
  case 'jumptest':
     this.aiRight = true;
     if (!this.jumped && p.body.blocked.down) { this.aiJump = true; this.jumped = true; this.apexY = p.y; }
     else if (this.jumped) { this.apexY = Math.min(this.apexY, p.y);
       if (p.body.blocked.down) { this.log('jump apex=' + Math.round(this.apexY)); this.setStage('doublecheck'); ...
```
Let me write a compact state machine with a timer per stage. Actually, I could write it as: each stage is a function evaluated every frame; it returns the next stage name when done.

I'll implement:

```
autoStages: [
  { name:'runRight', run: function(s){ s.aiRight = true; return s.player.x > 260 ? 'jumpTest' : null; } },
  { name:'jumpTest', run: function(s){
      s.aiRight = true;
      if (!s._jumpDone && s.player.body.blocked.down) { s.aiJump = true; s._jumpDone = true; s._apex = s.player.y; s._jumpCount = 1; s._jumpEndY = 0; }
      if (s._jumpDone) {
        s._apex = Math.min(s._apex, s.player.y);
        // if airborne and player jumps again... 
      }
      if (s._jumpDone) {
        // hold jump key for 800ms to attempt a double jump
        s._airTime = (s._airTime||0)+1;
        if (s._airTime > 50) { s.log(...); return 'land'; }
        s.aiJump = true;
      }
      return null;
  }},
  ...
]
```

Hmm, keeping jump held while airborne tests double jump; if double jump were allowed the player would rise again — detected by apex taking a second dip. Simple log of apex is enough: if the apex y is much lower than expected single-jump height, something's wrong.

Stage list:
1. runRight: run right until x>250.
2. jumpTest: jump, hold jump 40 frames, then log apex, stage land.
3. land: release all until blocked.down; log; stage platformApproach.
4. platformApproach: run right until player.y < 470 - 36 + few... hmm need to jump onto the platform at 300,470. Running right at x=250 jumping... the platform is at 300..428, top y=470, which is 150 above ground 620 — single jump height ~125px, so we can't reach 470 from the ground directly! 620-470 = 150 > 125. Hmm. Can't reach that platform from the ground.

That's a problem for completability! Let me reconsider platform heights: max jump height = v²/(2g) = 560²/(2*1250) = 313600/2500 = 125px. So a platform 150px above ground is unreachable directly. Need either lower platforms (≤ ~110 above ground for comfortable) or reachable in chains.

Also horizontal jump distance: air time for jump from ground back to ground = 2*560/1250 = 0.9s at 215px/s → 193px horizontal. So gaps up to ~64-100px are fine, and gaps of 100 px wide are fine (we have gap 64, 80, 80, ...). Good.

Let me re-audit platform heights: y=470 is 150 above ground → unreachable. y=440 → 180, worse. All platforms are too high! Need to redo: platforms should be at most ~110px above the surface they're reachable from, and chains matter (jump from platform to platform ≤110 steps).

Ground top 620. First platform should be at y ≈ 510-540 (80-110 above ground). Then next at 510-110=400 max above it. Let me redesign platform y values:

- 300, y=520 (100 above ground) — reachable
- 470, y=420 (100 above 520) — but horizontal distance from 300..428 platform end (428) to 470 → gap 42, fine.
- 690, y=470: reachable from ground (150)? No. From platform 470-420? Platform at x 470..598, y=420. 690 is 92 to the right, and 50 below — falling, fine.
- 1090, y=520 (100 above ground) ✓
- 1180, y=420: from 1090..1218 at y=520 → 100 above ✓
- 1440, y=520 ✓
- 1520, y=420 from 1440..1568 y=520 ✓
- 1800, y=520 ✓ (gap 1664..1744 then 1744..2096 ground — 1800 is above ground at 1744-2096? yes 1800 within; 100 above ✓)
- 2020, y=420: from 1800..1960 y=520, gap 60, 100 above ✓
- 2260, y=520: ground 2176..2464 ✓
- 2620, y=520: ground 2544..2992 ✓
- 2860, y=420: from 2620..2748 y=520, gap 112, 100 above ✓
- 3150, y=520: ground 3072..3488 ✓
- 3380, y=420: from 3150..3278 y=520, gap 102 ✓
- 3680, y=520: ground 3568..4400 ✓
- 3940, y=420: from 3680..3840 y=520, gap 100 ✓

Coins then must be above platforms: coin y = platY - 40ish, e.g. 470 for a 520 platform. And gap-hopping coins at ground-60ish.

Let me rewrite COIN_SPOTS and PLATFORMS y values. Also the level is completable on the ground alone (gaps ≤ 80) so platform heights are for coins. But requirement says solid platforms with gaps — the ground segments and floating platforms. Both exist.

Actually careful: gap widths: 576→640 = 64; 960→1040 = 80; 1328→1408 = 80; 1664→1744 = 80; 2096→2176 = 80; 2464→2544 = 80; 2992→3072 = 80; 3488→3568 = 80. All 80 → jumpable (193px reach). Good.

Now also verify the flag is reachable on the last segment. Yes.

Let me now update PLATFORMS y values and COIN_SPOTS accordingly. Coin spots (x,y) with y = platY - 40 (for y=520 → 480; for y=420 → 380). Let me recompute coin list to be near platforms:

PLATFORMS new:
1. {x:300,y:520,w:128} → coins at 340,480 / 372,480
2. {x:470,y:420,w:128} → coins 510,380 / 542,380 (360? no: 420-40=380)
3. {x:690,y:470,w:96} — 470 is 150 above ground → unreachable from ground; reachable from platform 2 (470..598 y=420)? x 690 is 92 right, y 50 below → yes, jump/fall reachable.
   coins: 710,430
4. {x:1090,y:520,w:128} → 1130,480 1162,480
5. {x:1180,y:420,w:96} → 1210,380
6. {x:1440,y:520,w:128} → 1480,480 1512,480
7. {x:1520,y:420,w:96} → 1560,380
8. {x:1800,y:520,w:160} → 1850,480 1882,480
9. {x:2020,y:420,w:96} → 2060,380
10. {x:2260,y:520,w:128} → 2300,480
11. {x:2620,y:520,w:128} → 2650,480 2682,480
12. {x:2860,y:420,w:160} → 2900,380 2932,380
13. {x:3150,y:520,w:128} → 3190,480
14. {x:3380,y:420,w:128} → 3420,380 3452,380
15. {x:3680,y:520,w:160} → 3720,480 3752,480
16. {x:3940,y:420,w:128} → 3980,380 4012,380

Plus ground-level coins (y = 570) in a few places, and coins over gaps at y≈560 (falling collect). Keep some ground coins: [760,570],[792,570] (over gap 640-960? no, on ground). Let me add a few on ground segments and over gaps:
- [900,560] over gap 960-1040? Actually gap between 960 and 1040 → put coins at 980,570 (in the air over the pit).
- Similar over other gaps: 1360,570; 1700,570; 2130,570; 2500,570; 3020,570; 3520,570.
- Ground coins: [400,570],[430,570] start area; [2600,570]; [4200,570].

Total: 16 platforms coins count: 1(2)+2(2)+3(1)+4(2)+5(1)+6(2)+7(1)+8(2)+9(1)+10(1)+11(2)+12(2)+13(1)+14(2)+15(2)+16(2) = 2+2+1+2+1+2+1+2+1+1+2+2+1+2+2+2 = 26. Plus ground 9 = 35 coins. Good.

Also enemy on platform: {x:3700, onPlat, y: 520-24=496}. Update that.

Also verify platform 3 at 690,470 reachable: from platform 2 (x 470..598, top 420). Jump from 420 → up 125 → apex y=295, and horizontal 193 → can reach x ≈ 598+193 = 791 while descending to y=470. Landing on platform 3 top at y=470, x 690..786. Yes reachable.

Also need: coins above platform 2 at y=380 — from ground? Platform 2 at 420 is 200 above ground — unreachable from the ground but reachable from platform 1 (520, x 300..428 → jump 125 up → can reach y 395; need 380... apex 520-125=395, so 380 is 15px too high!). Hmm. Tight. Let me lower the second-tier platforms: use y=440 (80 above 520) instead of 420, so coins at 400. Then from platform at 520, jumping 125 → apex 395 < 440 ✓ reachable.

Let me set tier-2 y=440 and coins at y=400. And tier-1 y=520 (100 above ground 620: apex 620-125=495 < 520 ✓).

Recheck platform 3 (690,470): from tier-2 platform (470..598, top 440) falling right to 470 — fine.

Also check the enemy on the platform at 3680 with y=440-24=416: update.

Let me now also double check horizontal reach for chain jumps from platform 1 (x 300..428) to platform 2 (x 470..598): gap 42 ✓.

Now, also the 80px ground gaps: player must not fall. Fine.

Now let me rewrite the level arrays and add the autopilot test hook.

One more consideration: the enemy patrol on the ground may walk into the gaps? No, they patrol between left/right bounds on the ground. Enemy at 4200 left 3800 right 4380 on the last ground segment 3568..4400 ✓.

Enemy at 900: patrol 660..940 on segment 640..960 ✓.
Enemy at 1200: 1060..1310 on 1040..1328 ✓.
1500: 1420..1650 on 1408..1664 ✓.
1900: 1760..2080 on 1744..2096 ✓.
2400: 2190..2450 on 2176..2464 ✓.
2750: 2560..2980 on 2544..2992 ✓.
3300: 3090..3470 on 3072..3488 ✓.
300: 180..540 on 0..576 ✓.
520: 380..560 ✓.

Good. Now edit the file.

Now add the autopilot test hook (toggle with 'P') to verify physics via keyboard presses. I'll add:
- in create: this.auto = false; keyboard P toggles; a stage runner.
- in update: use ai flags when auto.

Let me restructure update's input block and add autoUpdate.

Now I removed the `if (this.gameOver) { return; }` guard at the top — but I still need it. The stage machine sections after input assume the game is running. Let me re-read the update function and add the gameOver guard, and also add the auto test methods.

Let me read the current update region.

Good. Now I need to add the gameOver guard at the start (so the player stops and the auto machine doesn't run), plus toggleAuto/runAuto methods. Let me insert the guard right after `var left, right, jump;` — actually better: keep the auto runner call, then after the input application add:

```
      if (this.gameOver) {
        this.player.setVelocityX(0);
        return;
      }
```
placed before the movement application but after auto runs. Simplest: put the guard right before `if (left && !right)`.

Then add methods toggleAuto and runAuto with a stage list, inserted before `collectCoin` or after `updateHUD`.

Stage machine design (each stage is a function `fn(scene)` returning next stage name or null):

stages:
1. 'start': release all; when blocked.down → 'runRight'
2. 'runRight': aiRight=true; stop when player.x >= 250 → log; 'jumpTest'
3. 'jumpTest': aiRight=true; when blocked.down and not jumped → jumped=true, aiJump=true, apex=y, t0=time; while jumped keep aiJump=true (holding) and track min y; after airborne for 900ms → log apex + onFloor, then 'doubleJumpAttempt'... Actually holding jump the whole airtime is exactly the double jump test. Log apex height relative to takeoff: startY - apexY should be ~125.
   next stage: 'landPlatform': release jump; aiRight true until x >= 250... hmm, need to get to the platform at 300,520 which is left of 250? No: platform x 300..428. Run right until x >= 300 and then jump onto it.
   Let me do: 'runToPlatform': aiRight until x>=330 → 'jumpToPlatform'
4. 'jumpToPlatform': aiRight + jump when blocked.down; track; success when player.y < 480 && blocked.down → log 'landed on platform y=' ; next 'coinPickup'
5. 'coinPickup': from platform at 520 (top), coins at (340,480),(372,480) — player on the platform at x~330; move right to collect: aiRight until coinCount >= 1 → log 'coins=' + coinCount; next 'landAgain'
6. 'landAgain': run right off the platform, land on ground; wait until blocked.down and y > 560 → log; next 'enemyStomp'
7. 'enemyStomp': run right toward enemy #1 (x=300 patrol 180..540). Hmm, that enemy is back at x~180-540 after patrolling. Our player is now around x~450-500 on the ground. Risky. Better: approach the enemy from the left while it's at patrol right... it's unpredictable.
   Alternative: just walk right into the enemy and verify that either stomp or death happens — logging which. The requirement is: side contact → loss. Let's do: 'walkToEnemy': aiRight until gameOver → log result (gameOver true = 'side contact -> GAME OVER' correct, or enemy destroyed = 'stomp'). Since we won't jump, it's a side contact → GAME OVER expected. Good, this tests the loss state. Then next 'restartTest'.
8. 'restartTest': wait ~600ms, then call restart() (the global) and log post-restart state after 500ms: player x should be 90, coins 0, camera scrollX 0.

Note: restart() uses scene.restart() which resets; the new scene has auto=false, and stage machine stops. Good. Then press P again to re-run.

Let me implement. For logging, prefix '[AUTOTEST]'.

Implementation:

```
    toggleAuto: function () {
      this.auto = !this.auto;
      console.log('[AUTOTEST] autopilot = ' + this.auto);
      if (this.auto) {
        this.stage = 'start';
        this.stageT = 0;
        this._jumped = false; this._apex = 0; this._takeoff = 0;
        this.aiLeft = this.aiRight = this.aiJump = false;
      } else {
        this.aiLeft = this.aiRight = this.aiJump = false;
      }
    },

    runAuto: function () {
      this.stageT += this.game.loop.delta;
      var p = this.player;
      var floor = p.body.blocked.down;
      var s = this.stage;
      var act = {
        start: function (me) {
          me.aiRight = me.aiLeft = me.aiJump = false;
          if (floor) { me.logState('standing at start'); me.stage = 'runRight'; }
        },
        runRight: function (me) {
          me.aiRight = true;
          if (p.x >= 250) { me.logState('ran right'); me.stage = 'jumpTest'; }
        },
        jumpTest: function (me) {
          me.aiRight = true; me.aiJump = true;   // hold jump: tests double-jump
          if (!me._jumped && floor) {
            me._jumped = true; me._takeoff = p.y; me._apex = p.y;
            console.log('[AUTOTEST] jump takeoff y=' + Math.round(p.y));
          }
          if (me._jumped) { me._apex = Math.min(me._apex, p.y); }
          if (me._jumped && !_inAirSince) ...
        },
        ...
      };
```
Simplify jumpTest: when jumped and (me.stageT > 1000) → log apex and takeoff, release, next 'jumpToPlatform'. Since airtime is ~900ms, 1000ms after stage start... but stageT starts at 0 when entering. Taking off happens within ~1 frame of entering. So by 1000ms we're back on the floor or nearly. OK: log at stageT>1100 with 'onFloor'.

Let me use a helper: `me.stageT` reset on stage change; I'll add that in runAuto: if (this.stage !== this._lastStage) { this.stageT = 0; this._lastStage = this.stage; } else this.stageT += delta.

Write act as a map of functions taking (me).

Stages:
- start
- runRight
- jumpTest (hold jump; log apex rise = takeoff-apex)
- toPlatform: run right until x >= 330
- jumpToPlatform: run right + jump on floor; wait until floor && p.y < 480 → log 'landed on platform' else if stageT > 2500 → 'FAILED to land'
- getCoin: keep aiRight until coinCount >= 1 → log; then stop
- dropToGround: aiRight true until floor && p.y > 570 → log
- walkToEnemy: aiRight until gameOver (or 4000ms) → log result with state
- restartTest: after 500ms call restart() and after another 600ms log final state via a delayedCall.

Since after restart the auto flag is off, the final log must use a delayedCall from the old scene — but scene.restart destroys... the old scene's time events are removed on restart? scene.restart shuts down the scene, which clears time events. So do the final log differently: set a global flag `window.__pendingTestLog = {'x':...}`. Simpler: in the restart stage, use a plain setTimeout (outside Phaser's clock) — survives scene restart. Then after 700ms, log window.__scene state. Good, use setTimeout.

Let me write the code.

Note: `restart()` is defined inside the IIFE as a function declaration, so accessible. Good.

But careful: in create, `hideOverlay()` is called. On restart after game over, hideOverlay is called in create too. Good.

Also the `update` function signature has (time, delta) but I use this.game.loop.delta. Fine.

One issue: the gameOver early-return path calls runAuto() so the restart scheduling happens. Good.

Now reload and press P.

Good, level renders with 37 coins and reachable platforms. Now press P to run the autopilot test.

Hmm — the autopilot started ("standing at start" logged) but the player isn't moving right. The stage 'start' transitions to 'runRight' on the next frame. The screenshot was taken mid-frame. But also: the console shows only 2 logs; the test takes several seconds. Since screenshots are instantaneous, the state may just be stale.

Wait, but the DOM shows coins 0/37 still. The test proceeds over a few seconds. Let me take another screenshot / motion to see. Actually the issue: does the browser tool's screenshot happen at a particular frame? The console log output only captured the last frames. Let me wait and then take another screenshot — but there's no "wait" action. The screenshot action itself advances frames ("Frame 1, +0ms"). Hmm, "Frame 1" suggests a new frame each action.

Let me just take a screenshot now (time passes between actions naturally).

Excellent results! Wait — some numbers look off:
- "apex y=381 rise=221px" — rise 221px?? Expected ~125. And y=381 seems too high. Something's off... Oh! It says `backOnFloor=false` and apex rise 221. Hmm, but the level's camera... wait, the player y coordinate. Takeoff y=602. Apex y=381 means the player rose 221px. That's way more than 125px.

Wait — did the player land on the platform at 470 (top) while jumping? No, apex is the max height reached mid-air.

Hmm, why 221? Let me recompute: gravity 1250, jump velocity -560: rise = 560²/(2*1250) = 313600/2500 = 125.4px. So 221 is wrong... unless the player was standing on something? No, it was on the ground at y=602.

Oh wait! I see — `me._apex = Math.min(me._apex, p.y)` — p.y is the player's y position, not the body's. That's fine, same thing.

Hmm, unless the jump happened twice within a few frames: `if (jump && this.player.body.blocked.down)` — after the first jump, blocked.down may still be true for a frame or two? Actually in Arcade physics, blocked.down is set during collision processing each step. After setVelocityY(-560), the body moves up; on the next step, blocked.down would be false... unless collision detection still reports touching. Hmm, but Phaser has a known behavior: when you set velocity in preUpdate/update, the body's blocked flags... Actually the update order in Phaser: scene.update() is called, then physics world update? No — Arcade Physics world updates before the scene's update? In Phaser 3, the physics world 'update' event happens... The Scene systems order: `sceneUpdate` (calls scene.update) then... Actually Phaser's Scene: `sys.step()` → emits PRE_UPDATE, UPDATE (scene.update), then physics world.step? Let me recall: ArcadePhysics world is stepped in the scene's update event... In Phaser 3, `Scene.sys.step()` calls `this.events.emit(Events.PRE_UPDATE...)`, `UPDATE`, `POST_UPDATE`. The PhysicsManager adds a hook on the scene's UPDATE event? No, it uses `Systems.step`... The arcade world is updated via `world.update(time, delta)` registered on the scene's `Events.PRE_UPDATE`? Actually Phaser's ArcadePhysics registers on scene events PRE_UPDATE, UPDATE, POST_UPDATE. Hmm.

The known standard pattern is that setting velocity in `update()` works because the physics world steps after the scene update. Yes — arcade world update happens in the scene's UPDATE phase after scene.update (PhysicsManager listens to 'update' event with priority... `this.world.update` is bound to the scene's `Events.UPDATE`). Since our listener is added in create, order might matter: physics world update is called via `events.on(SceneEvents.UPDATE, this.world.update, this.world)` registered in the PhysicsPlugin boot, and our update() is called by SceneManager. Typically the standard is that physics steps after scene.update? Actually standard practice: modifying velocity in update() does affect the same frame — and jump works.

But double application: if blocked.down is still true the frame after the jump, jump velocity would be applied again, resetting to -560 (not adding). Setting velocity again to -560 wouldn't increase the rise; it would just cancel a little upward movement that already happened. That would reduce the rise, not increase it.

So rise 221 is suspicious. Unless the player was standing on a platform? The player at x=255 on the ground at y=602 — grounded. Then jumpTest sets aiRight = true and aiJump = true. Hold right → moving right at 215px/s. Over 0.9s of air time → 193px horizontal, so at apex x≈255+96=350 — that's right at the platform 1 (x 300..428, top y=520)! So the player, at the apex y=381 (above 520), descends onto the platform at 520. That explains intercepting. But the apex is still 221px above takeoff.

Hmm wait, maybe the takeoff y=602 is the player's center... The player body bottom = 602 + 18 = 620 (ground). Good. Jump apex y=381 → rise of the player's center by 221px. But physics says 125. So something else: maybe the coin collection tween? No.

OR: gravity Y is being overridden... `this.player.setMaxVelocity(320, 900)` — that's fine.

Hmm, maybe the level's physics world gravity is 1250 but the player has `body.setGravityY(-something)`? No.

Wait — maybe the platform collision isn't the reason... Let me reconsider: `jumpTest` holds jump continuously. `blocked.down` is true again briefly right after jumping? If the physics world steps between scene.update calls and the body hasn't moved yet (one-tile collision detection?), blocked.down might remain true for a couple of frames, re-applying setVelocityY(-560) each frame, extending the jump. With 3-4 frames of reapplication (~50ms), the extra rise would be small (560*0.05 = 28px)... Not 96.

Alternatively: maybe `this.game.loop.delta` accumulation... no, irrelevant to physics.

Hmm, could the player be bouncing off something? Let me think about the actual numbers again: rise=221 with peak y=381. What if the player jumped twice: once at y=602 and later again mid-air at y≈477 (i.e., after rising 125), giving another 125 rise → apex ≈ 477-125 = 352. Close to 381 but not exact. A double jump when allowed would give exactly ~250px rise (602-352=250). We measured 221 → hmm, close-ish. That suggests a double jump IS happening!

Wait: how? `if (jump && this.player.body.blocked.down)`. If the player passes over a platform edge and blocked.down becomes true momentarily while airborne... At x 300..428 the platform top is 520; the player's apex is 381 < 520... they don't touch it mid-air. But wait — maybe the player DID land on the platform at 520 (which is at x 300..428) on the way up? Takeoff at x=255 running right at 215px/s. Time to reach x=300 is ~0.2s, at which point y = 602 - (560*0.2 - 0.5*1250*0.04) = 602 - (112-25) = 515. So at x=300 the player's y ≈ 515, and the platform top is at 520 → the player is still above/at the platform top! So the player lands on the platform at 520 while still moving up?? No: at x=300, y=515 which is ABOVE the platform top (520), so the player would rest/collide with the platform top → blocked.down = true → another jump applied while standing on the platform (legal). Then rise another ~125 from 515 → apex ≈ 390. Combined with being at 515 (87 above takeoff) → total rise 212. That matches 221!

So it's not a double-jump bug; it's the auto-test path running right into the first platform and jumping off it. The physics is correct: the player was standing on the platform.

So the "no double jump" check is inconclusive from that test. I should verify explicitly with an isolated test: hold jump in a clear area with no platforms above, e.g., jump at x=90 in the start area and stay still (no right movement). Let me change jumpTest to not press right (just hold jump) so it stays at x≈90-130, clear of platforms (first platform at x=300). Then the apex rise should be ~125 and staying airborne should not rise again.

Let me update the jumpTest stage: me.aiRight = false there. Then 'toPlatform' stage handles moving right.

Also, the "LANDED ON PLATFORM y=413" — hmm, 413 means the player landed on the GROUND (620)? No, 413 is less than 520... it says y=413 with floor true and y<500 → landed on the platform at 440 (top 440 → player center y = 440-18 = 422, close to 413). Fine, that's the second platform (x 470..598 top 440). Good — reachable, since it's 100 above the first platform.

Then COIN COLLECTED count=3, back on the ground at x=710, camScrollX=188, and GAME OVER from side contact with an enemy. Then AFTER RESTART: player x=90 y=602, coins 0/37, camScrollX=0, enemies=11. All reset correctly.

One remaining issue: "AFTER RESTART ... camScrollY=180". Camera scrollY 180? The camera follow offset... The camera bounds are (0,0,4400,720) and the view is 960x540, so the camera can scroll up to 720-540=180 in Y. With startFollow and followOffset (0,0), the camera centers the player vertically: player y=602 → camera scrollY = 602 - 270 = 332, clamped to 180. So scrollY=180 initially, which is fine (the ground is at 620, bottom of the view at 800... wait, the view height is 540, so scrolling 180 shows y from 180 to 720. The ground at 620 is visible with 100px below. OK.

Hmm, but the initial screenshot shows the ground at the bottom-ish and lots of sky. That's fine — but it means the world bottom (720) is at the very bottom of the screen. Good.

Actually wait: with camera centered on the player, if the player jumps to y=380, the camera would follow up to scrollY=180 minimum... The camera scroll would want 380-270=110 < 180, so clamping keeps scrollY=180?? That's wrong: scrollY can range 0..180. If the player goes high (y small), the desired scrollY = player.y - 270 would be negative → clamped to 0. Fine.

Now, is the initial view too zoomed out? The level height 720 vs view 540: also there's dead space below ground (100px of dirt below ground level... wait, the ground tiles extend 3 rows below the top: 620+96=716, so the level bottom is 716+). Good.

Now, the remaining verification: no double jump. Let me fix the test and re-run. Also verify stomping an enemy (defeat + bounce) — the current test never stomps. Let me add a 'stompTest' stage before walking into the enemy: approach an enemy from the left and jump so we land on it. The enemy at x=300 patrols 180..540 (speed 55-80). I could position the player to land on an enemy deterministically... it's tricky but let's try: run right until player.x >= 150 (enemy somewhere left/right). Hmm, unpredictable.

Alternative: add a dedicated deterministic stomp check: stop the first enemy's movement (set speed 0, position known) during the test? I can set `en.setVelocityX(0)` and freeze its patrol by setting a flag... but the update loop always sets velocity from en.dir. I could add a `frozen` property to enemies and skip updating when frozen.

Simplest: in the stomp test stage, find the first enemy; freeze all enemies (en.frozen = true) except a chosen one; set its x to a known position, e.g. 620 (on the ground), dir=0 (still). Then run right to x=560, jump, land on it → expect enemy destroyed and player bounce (velocity y < 0 after contact).

I'll add `frozen` support in the enemy update loop:
```
this.enemies.getChildren().forEach(function (en) {
  if (!en.frozen) { en.setVelocityX(...); ...flip... }
});
```
And for a frozen enemy, setVelocityX(0).

Then the stomp stage:
```
stompSetup: function(me){
  // freeze enemies and park one at a known spot
  me.aiRight = me.aiJump = false;
  me.enemies.getChildren().forEach(function(en, i){ en.frozen = (i !== 0); });
  var en = me.enemies.getChildren()[0];
  en.frozen = false; en.dir = 0; en.speed = 0; en.x = 640; en.body.reset(640, GROUND_TOP - 22);
  me.logState('enemy parked at ' + Math.round(en.x));
  me.stage = 'stompRun';
},
stompRun: run right; when p.x >= 560 → 'stompJump'
stompJump: aiRight = true; if floor → aiJump = true (only once); after contact: check if the enemy is destroyed and player velocity y < 0 → log 'STOMP OK'. Wait until enemy no longer active → log; then next 'gameOverTest'
```
To detect the stomp: track `me._stompEnemy = en`. When `en.active === false` → log 'STOMP OK, bounce velocityY=' + round(p.body.velocity.y). Then stage 'gameOverTest' where we walk right into another enemy (frozen, at a known x) to test the loss state.

Actually careful: after stomping, I want to verify the player bounced: velocity.y < 0 right after the contact. Let me capture p.body.velocity.y at the moment enemy.active goes false.

Then for the loss test: unfreeze enemy #2 at x=900 and walk right into it → gameOver expected → then the restart verification runs.

Hmm, but the game-over handler currently checks `if (this.stage === 'walkToEnemy') && this.gameOver`. I'll generalize: check a flag `this._endStagePending`.

Let me restructure the auto test stages:
1. start
2. runRight (to x>=250)
3. jumpTest (hold jump in place, no horizontal; verify single jump rise ~125 and no re-rise)
4. landWait (until floor; log)
5. toPlatform (run right to x>=330)
6. jumpToPlatform (run right + jump on floor; land on platform)
7. getCoin (collect coin)
8. dropToGround (run right, land on ground)
9. stompSetup / stompRun / stompJump (stomp enemy, verify defeat + bounce)
10. lossTest (run right into a parked enemy → game over)
11. restart verification via setTimeout.

That's a fair amount but straightforward. Let me rewrite the whole acts block and add `frozen` support.

Given the time budget (I've used maybe 8 minutes), let me be efficient but careful. I'll replace the runAuto acts block.

Note: in update, the gameOver early return path calls runAuto() only if auto — good, and the restart scheduling is inside runAuto. But the scheduling check requires this.stage === 'lossRun' and gameOver. After gameOver, the update returns early but runAuto is called → good.

Also in the lossRun/gameOver path: the player collides with the frozen enemy and dies. Good.

Wait — one issue with the frozen enemy check in lossRun: it will die when contacting. But what if it lands and doesn't reach? 3s timeout.

Another: the enemy body reset — `en.body.reset(x, y)` for a dynamic body; y = GROUND_TOP - 11 (center of a 22-tall body? The enemy texture is 24x22, body 22x20 centered → offset (1,1), so body top = y - 11, bottom = y + 11. To place the body bottom at GROUND_TOP (620), y = 620 - 11 = 609. I wrote GROUND_TOP - 11 = 609. ✓.

For setPosition I used GROUND_TOP - 22 = 598 which puts the enemy's body bottom at 609, slightly above the ground — it'll fall 11px. Fine, but simplest is to use body.reset with the right y, which sets both. I did both setPosition and body.reset; body.reset wins. OK.

Also, the stomp enemy at 660 - it's on the ground segment 640..960. ✓ And the player runs from ~580 to the enemy at 660.

Also: I should double check `en.body.reset` exists — yes for dynamic bodies.

Now re-run the test.

The screenshot shows the player isn't moving right — it's still at x=90. That's odd because the previous run moved. Perhaps the 'motion' tool would help; but let's check with the console via inspect? The inspect tool shows DOM but not arbitrary JS eval.

Wait — the screenshot only shows the last frame at the moment of capture. The test progresses in real time; at the time of the screenshot, maybe the player was still in 'start' stage or... no, the player should have moved right by 250px.

Hmm, but this screenshot happens right after. It's possible the tool takes a screenshot immediately (same frame). Let me use the 'motion' action which captures frames over time.

Now let me check the full sequence that followed. Let me re-trigger and collect full logs.

The logic looks correct. The problem must be that after gameOver, `runAuto` is still called (from update's gameOver branch), but the game-over branch sets velocityX(0) and then returns — wait no, it calls runAuto before returning, and runAuto sets `me.aiRight = true` for lossRun, but that comes after `this.player.setVelocityX(0)`. So aiRight is ignored. Fine.

But wait — gameOver is set when the enemy hits. In the last run, GAME OVER with 0 coins. That means the player died early. Hmm.

Actually, the issue: after the reload, `P` is pressed. But the reload happened and the autotest ran the previous version? No, reload loads fresh HTML with the new acts.

Hmm, but the result was "GAME OVER, coins 0" quickly (within 2 sec). Actually the motion capture only shows 2 seconds. The log shows only "standing at start". Then GAME OVER.

Wait — this could be a stale scene: `window.__scene` and `restart()` refer to the scene captured at ready. That's fine.

Let's think about what's failing. Maybe the "P" keypress is being received twice or the autopilot starts but the player immediately falls? "Coins collected: 0" and GAME OVER. Where would the player die? Possibly the enemy parked at 660 (stompSetup) killed the player earlier... no, coins 0 means it died before collecting coin.

Hmm, actually maybe the autopilot got confused: after `me.stage = 'done'`, `done` clears flags. But GAME OVER with 0 coins...

Let's actually check: is it possible the P key triggered while auto was already true, toggling off? No, log shows autopilot=true once.

Another possibility: `hitEnemy` triggered because a patrolling enemy (e.g., x=300 or x=520, left 180-540) walked into the player who was running right through. In the original design, the first enemy patrols x in [180,540] on the ground, and the player runs right to 250 at y=602 — they'd collide! In earlier runs the player did collide but got lucky. Actually in the earlier full test, the player at x=251 got hit... no wait, it jumped over it.

Hmm, actually in the second motion run the log stopped after "standing at start" and no "ran right" — meaning it died before reaching x>=250. The enemy at x=300 patrolling left toward the player: player at 90, enemy moving left at ~55px/s... 210px gap → ~2 sec. But death was immediate-ish.

Actually maybe the player died because of the flag overlap? No.

Let me just add more logging and re-run. Actually, a simpler explanation: `P` keydown handler calls `toggleAuto` which resets the stage to 'start' and sets `this._lastStage` — not reset! `_lastStage` is still 'lossRun' from the previous run, so on first runAuto after toggling, `this.stage ('start') !== this._lastStage ('lossRun')` so stageT resets to 0 — that's fine actually.

Hmm, wait. Actually the previous run ended in gameOver and `_restartScheduled` was true from previous run → after reload it's fresh.

Let me look more carefully: after restart(), a NEW scene is created, but `toggleAuto` and state are new. However the old scene's setTimeout already fired. Fine.

Let me consider that the death is from the enemy at x=300 moving left. The player starts at x=90 y=602 on the ground. Enemy patrol left bound is 180, speed ~55-80px/s. It takes ~1.5s to reach x=180. Player running right at 215px/s reaches 250 in ~0.75s. They'd meet around x≈150-200... collision possible! In the previous successful run the player was at 251 and logged. So it's borderline — timing dependent. In the failing run, they collided → side contact → GAME OVER with 0 coins.

So the test is flaky. I should make the stomp/loss test robust by parking ALL enemies frozen at the very start of the autotest (in 'start' stage), so only scripted enemies are used.

Let me do that: in toggleAuto, freeze all enemies immediately. Then stompSetup/lossSetup unfreeze a specific one.

Also for platform landing test, I should reach the coin. Let me restructure: park enemies off at start.

Let me apply that fix.

The problem: the toPlatform stage runs right, but the platform at x=300 y=520 is above the ground at 620. The player at x=331 y=602 is already past the platform's left edge... wait, at x=331 they'd be standing under the platform. Wait — they DID reach x=331 without jumping. But wait, in the earlier run they LANDED on the platform at y=413 (which is odd — platform y=520, so landing y should be ~513). Hmm, that was a previous level layout. Now y=520 platform means the player standing on it would be at about 520-18=502. So logState said "at platform edge x=331 y=602 onFloor=true" — they're on the ground. Then jumpToPlatform stage: it runs right and jumps when floor. But the check `if (floor && p.y < 500)` — when standing on the platform, y would be ~502... Hmm 520 - 16 (half height) - 1 = 503. That's not < 500! So it never triggers the success. It failed after 2.6s. That's the bug in the test threshold, not the game. Wait but then the y reported "FAILED to land on platform, y=602" means they didn't get on the platform either. Let's compute: platform at x=300, w=128, so spans x=300..428. The player passes x=330 at y=602 on the ground. Then the stage jumpToPlatform: runs right, jumps when floor. The player is on the ground moving right. It jumps. From the ground at y~602 (bottom 619), a jump rises ~120px to y~500. Platform top is 520, player bottom when standing is ~519. So jumping straight up from the ground at x=330... hmm, actually when the player jumps up at x=330, they'd hit the platform bottom at y=520+16 = 536? The player height 32, center y=520-16... wait the player's body bottom when on ground is 619; on the platform the center is 520-18=502 (body bottom 518). Jumping from ground with center 602: body bottom 618, rises 120px → center 482, body bottom 498 — that's above the platform top (520)?? No: body bottom 498 is above 520 in screen coordinates (smaller y = higher). So they'd clear the platform top and land on it. Hmm, but they might hit the side of the platform first. The platform's left edge is at x=300; player at x=330 is already horizontally overlapping the platform. So jumping up from x=330 → player body bottom rises past 520 → lands on platform top.

But the log says final y=602, meaning it never got up there. Wait, actually there's an issue: the stage check `if (floor && p.y < 500)`. Standing on the platform: player center = 520 - 18 = 502 (body height 32, half=16). Hmm, I set body.setSize(15,32) with offset (4,4) — texture is 24x36, so body bottom is at y offset 36 from top... Actually with offset (4,4) and height 32, body spans from y+4 to y+36 relative to the top-left of the 36-tall texture. Texture top-left = player.y - 18. So body bottom = player.y - 18 + 36 = player.y + 18. On the platform (top y=520), body bottom = 520 → player.y = 502. So the check should be `p.y < 505` or better `p.y < GROUND_TOP - 100` i.e. 520. Let me use `p.y < 520`.

But also why did it fail entirely? It ran right for 2.6s, passing under the platform (x=300..428) then... after 428 it continues right, and eventually the gap at 576..640 → falls into the pit → GAME OVER. Actually "FAILED to land on platform, y=602" logged at stageT>2600 — hmm, at that moment y=602 still. Then GAME OVER happened later (fall into gap).

So the question is whether the player jumped at all. aiJump = true when floor. And in the update, jump applies when `jump && this.player.body.blocked.down`. Since aiJump stays true continuously, blocked.down will be true on the first frame → jumps. Then it goes up, and while airborne blocked.down is false. Then it lands... but wait, will it land on the platform? Let's think: the player at x≈332 (passing through) jumps up. It will hit the platform's underside (body top at y+? let's compute: body top = player.y - 18 + 4 = player.y - 14). Player center 602 → body top 588, body bottom 620. Platform bottom edge = 520+32 = 552. Jumping raises the player; body top rises from 588 upward. When body bottom (player.y+18) goes above 552, i.e. player.y < 534, the player's body is fully above the platform's bottom... no wait, that means it overlaps the platform region. Collision resolution: the player moving up hits the platform's bottom → gets blocked downward (blocked.up) and stops. Actually Arcade physics: the player's body bottom would be at 552 when player.y = 534; above that the player's body overlaps the platform tile, and since the platform is static and immovable, the player gets pushed back down (blocked.up = true, velocity zeroed). So the player is stuck under the platform, cannot get on top! Because the player starts ON THE GROUND directly beneath the platform at x=330, which is under the middle of the platform.

Right — that's why the earlier version landed on it: in the earlier version the platform was at y=470, and the player approached differently. Hmm no. Actually in the earlier test it said "at platform edge: x=331 y=602" then "LANDED ON PLATFORM y=413". y=413 while on ground? That doesn't make sense either... unless the player was jumping. Hmm, in that earlier run, the jump test at x=274 already returned to ground, then ran right to 331 and jumped... it landed at y=413? That would be above the platform (470)... weird. Actually maybe in that older layout, platform 1 was at y=470, so standing on it means y=452. 413 doesn't match either. Hmm, could it have landed on the second platform (x=470, y=440)? No, x was around 331.

Hmm, actually maybe the sequence: player jumps from ground at x=331, passes UP through... no, static collision prevents passing.

Wait, maybe in the earlier version the player jumped and the check `p.y < 500` triggered while airborne mid-jump (y=413 at apex... no, apex was 481 in jump test; jumping from ground again gives apex ~480). Hmm, y=413? That's above the computed apex. Odd but whatever — the important thing is the old check was triggering falsely (mid-air, while passing upward through). Now with `p.y < 500` still... it reported FAILED, so it didn't trigger. And now GAME OVER from the pit.

OK so the real issue: my scripted "land on a platform" test needs a proper approach: approach the platform from the LEFT edge and jump onto it from outside (not from underneath). The platform at x=300..428 y=520 is 100px above the ground at 620 — that's exactly a max jump (120px rise), so it's reachable but tight from the ground. Hmm, is it reachable? Player standing on ground: feet at 620, need feet at 520 → rise 100px. Max jump rise from velocity 560 with gravity 1250 = 560²/(2*1250) = 125px. So yes, 100px rise is achievable, but only barely and must be well-timed (jump while moving right at the platform's left edge, x<300).

Hmm, but this is tight. Better: make the first platform lower, e.g. y=540 (80px above ground) to make the level comfortably playable. Actually, classic platformers have lower platforms. Let me adjust: make platforms reachable with comfortable margins. Platform 1: y=540 (80px rise). That's fine and still requires a jump.

Actually, let me reconsider the whole level: ground top at 620. Platforms at y=520 are 100px above ground — reachable but tight. Let me lower all the "first tier" platforms to y=530 or 540 and keep a chain upward. Simpler: shift platform rows up in tier structure:
- Tier A (directly reachable from ground): y = 520 is 100px — tight but OK. Hmm, for robustness in a playable game, I'd rather make them ~80px: y=540.

Let me restructure: platform tier1 y=540, tier2 y=450, tier3 y=360. And coins accordingly.

Actually wait. There's a subtlety: with pixelArt and arcade physics, jumping 100px up requires the player to hold jump (which gives full 560 velocity) — fine, we always apply the full jump velocity. Rise = 125px max, so 100px works with ~50px margin. It's fine but the timing to land on the platform's top rather than hit the side requires approaching from the left edge. It's playable.

But to make it more forgiving for both players and my automated test, let me lower tier-1 platforms to y=545 (75px above ground). Then jump onto them from the left edge is comfortable.

Also I should fix the scripted test: run right until x reaches the platform's left edge minus a bit (e.g. 280 for platform at 300), then jump while continuing right, and check landing on top (y < platform top).

Let me restructure the level platforms:
- P1: x=300, y=545, w=128  → coins at y=505
- P2: x=470, y=465, w=128 → coins at 425 (80 above P1)
- P3: x=690, y=500, w=96 → hmm, need care.

Let me just do a simpler and cleaner design:
Ground level 620.
Tier 1 platforms: y=545 (75px above ground)
Tier 2: y=465 (80 above tier1)
Tier 3: y=385 (80 above tier2)

Platforms:
1. {x:300, y:545, w:128} - tier1
2. {x:470, y:465, w:128} - tier2
3. {x:690, y:500, w:96} - tier between 1 and 2 (35 above tier1, 65 below tier2) - ok
4. {x:1090, y:545, w:128}
5. {x:1180, y:465, w:96}
6. {x:1440, y:545, w:128}
7. {x:1520, y:465, w:96}
8. {x:1800, y:545, w:160}
9. {x:2020, y:465, w:96}
10. {x:2260, y:545, w:128}
11. {x:2620, y:545, w:128}
12. {x:2860, y:465, w:160}
13. {x:3150, y:545, w:128}
14. {x:3380, y:465, w:128}
15. {x:3680, y:545, w:160}
16. {x:3940, y:465, w:128}

Coins on platforms at ~40px above each platform: tier1 coins y=505, tier2 coins y=425.

Also the stomp test parks an enemy at x=660 on the ground between segments (640..960 is ground, so x=660 is ground). Player at 580 → the player approaching from the left on the ground at 576.. the ground ends at 576! Segment 1 is x=0..576, then gap 576..640, then 640..960. So the player at 580 would be in the gap. Let me re-park the stomp enemy on a wider safe stretch: put the enemy at x=690 (between 640 and 960, 320 wide) and have the player jump onto it. Player start x=90. Player needs to get on the far side of the 64px gap at 576..640 (jumpable: max horizontal jump distance = speed 215 * airtime. Airtime for full jump: up 0.448s + down 0.448s ≈ 0.9s → 193px horizontal. So a 64px gap is fine).

Simpler: make the stomp test park the enemy at x=880 on the ground segment 640..960 (width 320). Player approaches from the left at ~x=760. Hmm, but the player has to cross the gap at 576-640 first. That's fine.

Even simpler: park the enemy near the start: segment 0..576 has room. Park at x=420, player approaches at 340 (well before 576). Jump from ~x=360 to land on the enemy at 420. Enemy at x=420 on ground, player jumps from ~350, travels right... player needs to come down on top of the enemy around x=420. Airtime ~0.9s * 215 = 193px horizontal — too far; the player would overshoot. Better: jump at x≈380 so they land around... hmm, jump distance for a full jump is ~193px. To land on a target, jump earlier and land on it: enemy at 420, so takeoff at 380 → landing at ~420 (40px later, i.e. 0.19s later). At 0.19s the player is near the apex (apex at 0.448s), so they'd be at height ~ 560*0.19 - 625*0.036 = 106-22 = 84px above the ground. The enemy is 22 tall, so the player (feet) at 84px above ground is well above the enemy → they'd descend onto it. Then stomp works, with a bounce.

Simpler approach: don't script a precise jump; just walk right and let the test detect stomp vs. loss. Park an enemy at x=420 with the player continuing to run right and jumping when close? That's fiddly.

Alternative approach for the stomp test that's robust: freeze the enemy at x=420, and in the script have the player run right and press jump when player.x >= 380 (jump once), continuing right. Then it should stomp the enemy. Let's compute more carefully: at x=380, the player jumps, velocityY=-560, vx=215. Enemy at x=420 with halfwidth 11. Enemy right edge 431, left edge 409. The player needs to descend with feet above the enemy's top (620-22=598... enemy body top ≈ 599).

Time to fall back to y where feet = 598 (i.e. the player center ~ 598-18=580, vs. the ground center 602): fall from apex. Player center starts at 602, rise 125 → apex 477. Time to apex 0.448s. Then to descend to center 580: fall 103px from apex: t=sqrt(2*103/1250)=0.406s. Total time from takeoff = 0.854s. Horizontal distance = 215*0.854 = 183px → x = 380+183 = 563. That's well past the enemy at 420. So they'd overshoot the enemy and continue right to the gap... Not good.

So instead: park the enemy further right, at x=563? Hmm. Let's make the takeoff at x=380 and park the enemy at x≈565 (landing point). But 576 is the gap start; 565 is close. Let's park the enemy at x=500 and jump from x=320: landing at 320+183=503 ≈ 500. 

But the player starts at x=90; the script must run right to x=320, then jump. Fine. But careful: the enemy parked at 500 is within segment 0..576 — good.

Also, does the player's stomp check `fromAbove` (player.body.bottom - enemy.body.top < 16) work at landing? At landing, the player's bottom ≈ enemy.top, so difference ≈ 0 → ok. And falling velocity > 20 → yes.

Then after the stomp, bounce: velocity -420 → rise 70px, fine.

Then lossRun: park another enemy at x=700 on the ground segment 640..960 (needs the player to cross the gap 576-640 — the player will run right and fall into the gap unless it jumps!). Hmm. So for the loss test, park the enemy at x=500 again (already dead? no, the stomp enemy). The loss test could reuse a freshly created enemy at x=200, and the player runs left? Simpler: park a fresh enemy at x=180 (left of the player's current position ~500) and run LEFT into it. Side contact → loss. The player runs left; `left` sets flip. That works and avoids the gap. But careful: the player must not run off the left edge (clamped at 16). Enemy at 180, fine.

Hmm, but after the stomp, where is the player? Around x=500 on the ground. Then run left to the enemy at 180 → contact → game over. 

Let me restructure the stomp/loss test:
- stompSetup: park a fresh/parked enemy at x=500 (on the ground segment 0..576).
- stompRun: run right until p.x >= 320.
- stompJump: run right; when floor and not jumped yet, jump; keep aiRight. Detect the stomp.
- lossSetup: create a fresh enemy at x=180, frozen=false, speed 0.
- lossRun: aiLeft = true (run left) until gameOver or timeout.

Note in `lossRun`, `me.aiLeft = true` — the update flips the player. Good.

Let me also handle: after the stomp bounce the player is in the air; running left is fine.

Now about the platform landing test: I'll use platform 1 at x=300..428, y=545. Approach from the left: run right until p.x >= 250 (well before 300), then jump while continuing right; the player rises and moves forward. Landing on the platform top requires the player to be above 545-... Let's compute: takeoff at x=250 (center y=602, feet 620). Rise to apex 125px → center 477, feet 495. Platform top at 545. So the feet cross 545 on the way up at: height 75px → time t: 560t - 625t² = 75 → t ≈ 0.146s. At that point x = 250 + 215*0.146 = 281. But the platform's left edge is at 300 — so the player is at x=281, not yet over the platform (the player's body spans ±7.5). So it continues up. Then it descends and the feet reach 545 again at t = (560+sqrt(560²-4*625*75))/1250 → 560²=313600; 4*625*75=187500; sqrt(126100)=355 → t=(560+355)/1250=0.732s. x at that time = 250+215*0.732=407. That's over the platform (300..428) — near its right edge (428). Hmm, the player's right edge is 407+7.5=414.5 < 428, so it lands on the platform. 

But if the takeoff is a bit later (x=270), landing at x=427 — marginal. To be safe, let me have the script take off earlier, e.g. at x=240, and check the landing y. Then landing at x≈397.

Then, after landing on the platform, the coins on the platform: coin at [340,505] — is it reachable while standing on the platform at y=545? The player's feet at 545, head at 513. The coin at 505 with radius 8 spans 497..513. Standing on the platform, the player's head is at 513 → touching the coin. Good, walking right collects it.

But the landing x = 397, and the coin at 340 is to the left → run left to collect. The script's getCoin stage runs right (aiRight). Let me make it run LEFT after landing (aiLeft). Since we land at ~397 and the coins are at 340 and 372, running left collects them. OK, but the player is on a 128-wide platform (300..428), so running left to 340 is safe.

Hmm, but wait: what if the player steps off the platform's left edge and falls? At x=340 it's fine (platform from 300).

Let me make the test: after landing on the platform, set aiLeft = true until coinCount >= 1 (the coin at 372 is crossed first). Good.

But hold on: is the coin overlapping detection with a static coin in a static group and the player? Yes, physics.overlap(player, coins). Note I use `this.coins = this.physics.add.staticGroup()` and create each coin with `self.coins.create(x,y,'coin')` then `refreshBody()`. Static group overlap works.

Also, the coin at [340,505] — hmm, is that above the platform (545) by 40px. The player standing on the platform has its head at 513, and the coin bottom is 513 — just touching. Overlap should trigger. The jump tween moves the coin ±6px, so it'll overlap. Good.

Alright. Also, in the earlier test, "COIN COLLECTED count=2" happened on the ground at y=570 (coins [400,570],[432,570]) — those were at the ground level. Fine.

Now, another thing to fix: the `toPlatform` threshold. Let me restructure the stages:

- runRight: run right until p.x >= 240.
- jumpToPlatform: aiRight = true; if floor && !jumped → jump (set me.jumped=true). Success when floor && p.y < 530 (platform top 545 → player center 527). Use `p.y < 535`. Timeout 2600ms → fail.
- getCoin: aiLeft = true until coinCount >= 1.
- dropToGround: aiRight = true until floor && p.y > 560.

Hmm, careful with dropToGround: after collecting the coin at ~340 on the platform, run right → fall off the platform's right edge (428) down to the ground (620) — the player lands on the ground at y=602 > 560. Good.

Let me also double check the "jump returned to the ground" check in landWait: p.y > 560 works.

One more consideration: the first jump test holds jump in place; the player is at x=274 after it. Then runRight until 240? Already past. Let me make the order: start → jumpTest (in place) → landWait → runRight (until x>=240; if already past, immediately) → jumpToPlatform...

Hmm, but at x=274 the player is on the ground; jumping right from there lands at 274+183 = 457 > 428 — overshoots the platform's right edge and lands... at 457? The platform ends at 428, so the player would be past it and land on the ground. Not ideal. So let me back up: after the jump test, run LEFT until x <= 200, then run right to 240 and jump. Let me add a `backUp` stage: aiLeft = true until p.x <= 200.

Then landWait → backUp → toPlatform (run right until x>=240) → jumpToPlatform.

Wait, actually the first jump test already ran right to 250 first (runRight stage). Let me reorder:
- start
- backUp: run left until p.x <= 150 (clear area for the in-place jump test)
- jumpTest: hold jump in place (max rise ~125px, no second rise)
- landWait
- toPlatform: run right until p.x >= 240
- jumpToPlatform: jump once at floor, keep running right, land on platform 1 (y<535)
- getCoin: run left to collect a coin
- dropToGround: run right, land on the ground
- stompSetup / stompRun / stompJump
- lossSetup / lossRun

That's a solid sequence. Let me rewrite the acts block.

Also fix the loss detection: `hitEnemy` → `lose()`.

And restart verification: after the loss, `restart()` is called → scene.restart(). The new scene's create() runs, resetting everything. Note: `window.__scene` is updated by the interval checker. Good.

One issue: `this.auto` etc. persist per-scene instance; after restart, a new scene instance is created (scene.restart re-runs create on the same scene instance? Actually scene.restart() restarts the same scene instance, calling init/create again — the same object, but our create resets the needed state. The old timers from the previous run (tweens, delayed calls) are cleared. Fine.

Also: the enemy frozen flag — after restart, new enemies are created without frozen. In toggleAuto we freeze them. Good.

Another important check: the autopilot's restart scheduling uses setTimeout, and it calls the global `restart()`. Fine.

Let me now write the new acts block, plus update the platform/coin level data.

Also I realize the stomp test needs the player to be on the ground when jumping. After dropToGround, the player is on the ground. Then stompSetup parks the enemy at x=500. stompRun: run right until p.x >= 320. But wait — after dropToGround, where is the player? It runs right off the platform at 428 and lands on the ground ~452. Then stompRun: p.x >= 320 is already satisfied → immediately goes to stompJump. Then it jumps when floor. Takeoff at ~452 → landing at 452+183 = 635 — that's past the enemy at 500 and into the gap (576..640)! Bad.

Let me set the stomp threshold: run right until p.x >= 300 (if already past... hmm). Better: after dropToGround, add a `stompBack` stage: run left until p.x <= 250. Then stompRun: run right until p.x >= 320 → jump. Takeoff at 320, landing at ~503. Enemy at 500. 

But careful: the player running left from 452 to 250 passes over the ground — fine. Note the coins at [400,570],[432,570] get collected — that's fine (coinCount increases, and getCoin already finished).

So the sequence: dropToGround → stompBack (left until 250) → stompRun (right until 320) → stompJump.

In stompJump: aiRight = true; jump once when floor. The player takes off at ~320, apex at 320+96=416, lands at ~503. Enemy at 500 → stomp. 

Let me be careful about the exact landing point: 215px/s * 0.854s = 183.6 → 503.6. Enemy at 500 with halfwidth 11 → 489..511. Player halfwidth 7.5 → 496..511. Overlap. Stomp triggered when the player's feet pass 598 descending with the horizontal overlap. Good.

Then the bounce. Then lossSetup parks a fresh enemy at x=180; lossRun: aiLeft = true until gameOver. The player (after bounce, around x=500 rising up to 477 then falling) runs left... but there's no floor under it while airborne — the horizontal velocity still applies. It moves left ~183px during the fall → lands around x=320 on the ground. Then continues left to the enemy at 180 → side contact → lose. 

But careful: could the player land ON TOP of the enemy while falling? The player is at x~320 falling; the enemy is at 180. The player's descent takes them left; by the time the player descends to the enemy's height (~at x=320... hmm, actually the fall to the ground takes 0.4s → 86px left → lands at ~417). Then it keeps running left and hits the enemy from the side → lose. Good.

Wait — but while running left on the ground, the player will reach the enemy at 180 and collide → side contact → gameOver. 

Also make sure the enemy at 180 is on the ground (segment 0..576) — yes.

Let me now write everything. Also the `lossRun` uses aiLeft.

One more thing: I should double-check the "secondRise" no-double-jump detection. Since we hold jump, if double-jump were allowed the player would jump again while airborne. Our code checks `if (jump && floor)`, so holding doesn't re-trigger. The apex rise ~121px confirms no double jump.

Let me write the new acts and level data now.

The stage logic has a flaw: `jumpToPlatform` checks `p.x >= 250`, but the player is already at x=274 when `landWait` finished, so `toPlatform` immediately transitions. Then `jumpToPlatform` starts from x=274 which is past the platform left edge at 300? No, 274 < 300, so it's approaching. Wait but it says FAILED to land on platform with y=602. The problem: the `stage` is set to 'jumpToPlatform' while the player is already at x=274 — that's fine, it should run right and jump. But the player never jumped? Actually the issue: in `jumpToPlatform`, `if (floor) { me.aiJump = true; }` — the player jumps, but since aiRight is also true, the player runs right. Platform at x=300 w=128 → left edge 300, top y=545. Player standing on ground at y=602 (body bottom ~618). Jumping straight up while moving right... at x=300 the player would be at x~300 rising. Hmm, it should work. But the result says FAILED with y=602 meaning it never got onto the platform. 

Wait — maybe the problem is that the stage transition happens in the same frame: `landWait` sets stage='toPlatform'; then in `toPlatform`, x=274 < 250? No, 274 >= 250, so it sets stage='jumpToPlatform' and logs. Then next frame `jumpToPlatform` runs. Player runs right and jumps. Hmm.

Actually the issue could be that the player lands on the platform but `p.y < 500` check: platform top is 545, player body center would be ~545-16=529, not < 500. That's the bug in the check! Earlier platform top was 520 and check was <500 which was borderline. Now platform top is 545 → player y ≈ 529. So the check `p.y < 500` fails, then after 2600ms it reports FAILED even though it landed. Let me change to `p.y < 560` (ground y is 602).

Also earlier with platform at 470 top (body y ≈ 470-18=452) the check passed. Now with 545 → 529. So fix threshold to `< 560`.

I have very little time left. Let me make this fix and one final quick verification.
