Let me rewrite this properly — the initial version had several issues with texture generation and physics.

The file is complete. Here's what's in `/tmp/ws/index.html`: **Features:** - **Procedural graphics** — all sprites (player, enemies, coins, blocks, ground, flag, clouds, bushes, hills) are drawn via Phaser Graphics and baked into textures at boot - **Side-scrolling platformer** — camera follows the player across a 6000px world - **Run & jump** — Arrow keys / WASD to move, Space to jump (with variable jump height) - **Stomp enemies** — fall onto goomba-like enemies to squish them (+100 pts); touching from the side costs a life - **Collect coins** — floating coins and coins above question blocks (+10 pts each, with floating score popups) - **3 lives** — fall into pits or get hit by enemies costs a life; respawn at start - **Goal flag** — reach the flag pole at the end of the level to win (with slide-down animation) - **Parallax scrolling** — sky, hills, clouds, and bushes scroll at different speeds - **Menu screen** — title screen with animated prompt - **Game over / win screens** — with score display and restart option - **No external assets** — runs fully sandboxed with only `phaser.min.js` loaded locally

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.
