Platformer built at `index.html` — single-file, offline, using `phaser.min.js` with fully procedural graphics. **Game: PIXEL LEAP** - **Movement:** ←→/A/D to run, ↑/W/Space or tap ▲ to jump (hold for higher variable jump, coyote time + jump buffer), side-scrolling camera with parallax clouds/hills - **Platforms:** Procedurally drawn brick platforms, ground with grass cap, green pipes — all generated via canvas `generateTexture` - **Enemies:** Brown Goombro patrols that reverse on walls/edges, squash & fade when stomped from above (+200, bounce), hurt player otherwise with invulnerability flashing & knockback - **Coins:** 40+ bobbing coins with shine (+100, pop animation), HUD tracks `SCORE` and `Coins x / total` - **Goal:** Flagpole at end (world width 4200px) with castle, sliding flag animation — win adds bonus, shows victory screen - **Polish:** Lives (♥♥♥), screenshake, synth SFX via WebAudio (jump/coin/stomp/hurt/win), touch pads (◀▶ + jump button), score popups, cloud parallax, Mute/Restart buttons, Start/Menu/Game Over overlays, pixel-art rendering No external assets — all textures (ground, brick, pipe, player run/jump, enemy, coin, flag, cloud, hill) drawn with Phaser Graphics at runtime.

EVALUATION

1/5 broken

Only the menu screen loads; a JS error prevents the actual platformer game from starting.

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.
