The `index.html` file has been created with a fully self-contained, procedural Mario-style platformer game. Here's what it includes: ### Key Features: 1. **Procedural Graphics**: - Player (brown with a head) - Platforms (brown blocks) - Enemies (red with eyes) - Coins (gold circles) - Pipes (vertical brown blocks) - Flag (red pole with a white triangular flag) 2. **Gameplay Mechanics**: - Left/Right arrow keys to move. - Up arrow to jump. - Stomp enemies to earn points. - Collect coins for extra points. - Reach the flag to win. 3. **Procedural Generation**: - Randomly generated platforms, enemies, and coins. - Scrolling camera to explore the world. 4. **No External Assets**: - Everything is drawn using Phaser's built-in `Graphics` API. ### How to Play: - Open `index.html` in a browser. - Use the **arrow keys** to move and jump. - Stomp enemies to defeat them. - Collect coins for points. - Reach the flag to win! The game is fully sandboxed and requires no network access. Enjoy!
