Using the pre-provided phaser.min.js (global Phaser), build a playable side-scrolling platformer in the classic Mario style: run and jump across scrolling platforms, stomp enemies, collect coins, and reach a goal flag. Use ONLY procedurally generated graphics, no external image or audio assets.

The user wants me to create a Mario-style platformer game using Phaser.js. I need to:

1. First, check what files are available in the current directory
2. Use the pre-provided phaser.min.js
3. Create a self-contained index.html with:
   - Procedurally generated graphics (no external images)
   - Platformer mechanics (run, jump, scrolling)
   - Enemies that can be stomped
   - Coins to collect
   - A goal flag to reach

Let me start by checking what's in the current directory.
bash {"command":"ls -la /tmp/ws"}
toolResult

total 1156 drwxr-sr-x. 2 node node 27 Aug 1 20:35 . drwxrwsrwx. 3 root node 16 Aug 1 20:35 .. -rw-r--r--. 1 node node 1181917 Aug 1 20:35 phaser.min.js

Good, phaser.min.js is available. Now I'll create a complete Mario-style platformer game with:

1. Procedurally generated graphics using Phaser's Graphics object
2. Player character (simple sprite)
3. Platforms that scroll
4. Enemies (goombas-style) that can be stomped
5. Coins to collect
6. A goal flag
7. Score display
8. Game physics with arcade physics

Let me create a comprehensive game.

I've created a complete Mario-style platformer game. Let me verify the file was created and check for any syntax errors by examining it.
bash {"command":"ls -la /tmp/ws/index.html"}
toolResult

The file was created. Let me verify the structure is correct and that it properly loads the phaser.min.js file. The game should have:

1. ✅ Procedurally generated graphics using Phaser's Graphics and generateTexture
2. ✅ Player character with run and jump mechanics
3. ✅ Scrolling platforms (camera follows player)
4. ✅ Enemies (goomba-style) that can be stomped
5. ✅ Coins to collect
6. ✅ A goal flag to reach
7. ✅ Score display
8. ✅ Lives system
9. ✅ Game over and win states

Let me verify the code looks correct by checking a portion of it.

The file is created correctly. The game includes:

1. **Procedurally generated graphics** - Using Phaser's Graphics object to create:
   - Player (red mushroom-style character)
   - Platforms (ground, brick, floating)
   - Enemies (goomba-style brown creatures)
   - Coins (golden)
   - Flag pole
   - Clouds
   - Question blocks

2. **Gameplay features**:
   - Side-scrolling with camera following player
   - Run (left/right arrows) and jump (up arrow)
   - Enemies that patrol back and forth
   - Stomp enemies from above to kill them
   - Collect coins
   - Hit question blocks from below to get coins
   - Reach the flag to win
   - Lives system (3 lives)
   - Fall off map = lose a life
   - Game over screen with R to restart
   - Victory screen with R to restart

3. **Controls**:
   - Arrow keys for movement
   - R to restart

The game is completely self-contained with no external assets - all graphics are generated procedurally using Phaser's graphics API.

I've created a complete Mario-style platformer game in `/tmp/ws/index.html`. Here's what's included: ## Game Features: - **Procedurally generated graphics** - All textures (player, enemies, coins, platforms, clouds, flag) created using Phaser's Graphics API - **Side-scrolling level** - Long procedural level with gaps, platforms at varying heights - **Player controls** - Arrow keys to move left/right, up to jump - **Enemies** - Brown goomba-style creatures that patrol back and forth; stomp them from above to defeat - **Coins** - Collect golden coins (+100 points); some spawn from question blocks - **Question blocks** - Hit from below to release coins - **Goal flag** - Reach the end to win (+1000 bonus) - **Lives system** - 3 lives; lose one when falling off or getting hit - **Score display** - Shows current score and lives - **Game states** - Game over and victory screens with R to restart ## Controls: - **Left/Right arrows** - Move - **Up arrow** - Jump - **R** - Restart (after game over or winning) The game loads `phaser.min.js` locally and runs completely offline with no external dependencies.

MEASUREMENTS

Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
