The user wants a side-scrolling platformer game using Phaser with procedurally generated graphics. Key requirements:
1. Run and jump across scrolling platforms
2. Stomp enemies
3. Collect coins
4. Reach a goal flag
5. No external assets - all graphics generated procedurally

I need to:
1. First check if phaser.min.js exists in the current directory
2. Create an index.html with CSS and JS inline
3. Use Phaser's graphics API to create all sprites programmatically
4. Implement platformer physics (gravity, collisions)
5. Create a simple level with platforms, enemies, coins, and a goal
6. Add player controls for running and jumping
7. Implement camera following the player
8. Add score tracking

Let me start by checking if phaser.min.js exists.

I'll create a side-scrolling platformer game using procedurally generated graphics. Let me first check if Phaser is available.

Great, phaser.min.js is available. Now I'll create a complete side-scrolling platformer with procedurally generated graphics. I'll need to:

1. Create a basic HTML structure with inline CSS and JS
2. Use Phaser's graphics API to generate all sprites
3. Implement:
   - Player character with run/jump physics
   - Side-scrolling camera that follows player
   - Platforms to jump on
   - Enemies to stomp
   - Coins to collect
   - Goal flag at the end
   - Score system

Let me create the game using Phaser's Graphics object to draw everything programmatically.

Perfect! I've created a complete side-scrolling platformer with procedurally generated graphics. Let me verify the file was created correctly.

I've created a complete side-scrolling platformer game! The game includes: **Features:** - **Procedurally generated graphics** - All sprites are drawn using Phaser's graphics API (no external images) - **Player character** - Red block with a face that can run and jump - **Side-scrolling camera** - Follows the player as they move right - **Platforms** - Brown platforms to jump across - **Enemies** - Brown Goomba-like enemies that move back and forth (stomp them from above!) - **Coins** - Golden coins to collect for points - **Goal flag** - Red flag at the end of the level to win - **Score system** - Earn points for coins (+10) and stomping enemies (+20) - **Game over** - If an enemy hits you from the side **Controls:** - **←/→ Arrow Keys**: Move left/right - **↑ Arrow Key**: Jump - **Objective**: Collect coins, stomp enemies, and reach the flag at the end! The game is fully self-contained in `index.html` with no external dependencies except phaser.min.js. Open it in any modern browser!
