The user wants me to build a top-down alien shooter game using Phaser.js. Let me plan this out:

1. Use the pre-provided phaser.min.js file
2. Create a single index.html file with all CSS and JS inline
3. Use procedurally generated graphics (no external assets)
4. Features needed:
   - WASD movement
   - Aim and fire (mouse control)
   - Waves of advancing aliens
   - Health system
   - Score system
   - Increasing difficulty

Let me create a comprehensive game with all these features. I'll use Phaser's graphics API to create all sprites procedurally.

Key components:
- Player ship (drawn with graphics)
- Alien enemies (drawn with graphics)
- Bullets (player and alien)
- UI for health, score, wave
- Wave system with increasing difficulty
- Collision detection
- Game over / restart functionality

Let me write this out.

I've created a complete top-down alien shooter game. Let me verify it's properly written and check that phaser.min.js exists in the current directory.

Both files are present. The game is complete. Let me summarize what I built:

1. **Player ship**: A cyan triangle-shaped ship drawn procedurally with graphics
2. **Controls**: WASD or arrow keys for movement, mouse to aim and click to fire
3. **Enemies**: Three types of aliens with different colors, shapes, and health
   - Type 1 (green): Basic, 1 HP, 10 points
   - Type 2 (purple diamond): Medium, 2 HP, 25 points
   - Type 3 (orange boss): Tough, 5 HP, 100 points
4. **Wave system**: Progressive waves with increasing difficulty, more enemies per wave
5. **Health system**: 100 health, displayed with color changes (green -> yellow -> red)
6. **Score system**: Points based on alien type × wave number
7. **Visual effects**: Starfield background, explosion particles, flash effects on damage
8. **Procedural graphics**: All sprites drawn with Phaser's Graphics API, no external assets
9. **Collision detection**: Bullets vs aliens, alien bullets vs player, player vs aliens
10. **Game over/restart**: Click to restart after dying
