The user wants me to create a Mario-style side-scrolling platformer using Phaser.js. The requirements are:
1. Single self-contained HTML file (index.html)
2. Use phaser.min.js from the current directory
3. Procedurally generated graphics only (no external images)
4. Features: running, jumping, scrolling platforms, stomping enemies, collecting coins, reaching a goal flag
5. No external resources or CDNs

Let me plan the game:

1. **Scene Setup**:
   - A scrolling camera that follows the player
   - Multiple platforms generated at different heights
   - Ground platforms with gaps

2. **Player**:
   - Sprite created with Phaser's graphics (rectangle-based)
   - Run animation (simplified)
   - Jump physics with gravity
   - Collision detection

3. **Enemies**:
   - Simple Goomba-like sprites
   - Walk back and forth
   - Can be stomped (player falls on them)
   - Kill the player on contact

4. **Coins**:
   - Yellow circles/rectangles that rotate
   - Collectible with collision
   - Score system

5. **Goal**:
   - A flag pole
   - Win condition when player reaches it

6. **Procedural Graphics**:
   - Draw player, enemies, platforms, coins, flag using Phaser.Graphics or cached drawings

Let me write this complete game:

I've created a complete Mario-style platformer game in a single HTML file. Let me verify that it works by checking the file structure and making sure everything is properly set up.

The game includes:
1. Procedurally generated graphics for all assets (clouds, hills, ground, bricks, pipes, enemies, coins, player, goal)
2. Side-scrolling camera that follows the player
3. Platform generation with ground segments, floating platforms, and gaps
4. Enemy AI that walks back and forth
5. Stomping mechanics
6. Coin collection with score tracking
7. Goal flag to reach for victory
8. Game over and win states
9. Particle effects
10. Procedural world generation

All graphics are created using Phaser's Graphics API and cached as textures, so no external images are needed.

Let me check if the phaser.min.js file exists in the directory.

Great! The phaser.min.js file exists. Let me create a simple test to make sure the game structure is valid by checking if the file can be parsed properly.
