I've created a complete side-scrolling platformer game in a single `index.html` file using Phaser. Here's what the game includes: 1. **Procedural Graphics**: - Player character with simple face - Platforms and ground - Coins that sparkle - Enemies with simple faces - Goal flag at the end 2. **Gameplay Mechanics**: - Run left/right with arrow keys - Jump with up arrow - Stomp enemies by jumping on them - Collect coins for points - Reach the flag to win 3. **Game Features**: - Scrolling camera that follows the player - Coin counter display - Win screen with final score - Restart button 4. **Physics**: - Gravity and jumping - Collision detection - Enemy movement patterns The game is completely self-contained with no external dependencies (other than the provided phaser.min.js). All graphics are procedurally generated using Phaser's drawing capabilities. You can open the `index.html` file in any modern browser to play the game. Use the arrow keys to move and jump. Try to collect all the coins and reach the flag at the end!

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.
