Top-down alien shooter · ministral-3b-2512

Using the pre-provided phaser.min.js (global Phaser), build a top-down alien shooter: move with WASD, aim and fire at waves of advancing aliens, with health, score, and increasing difficulty. Use ONLY procedurally generated graphics, no external image or audio assets.

It seems I cannot directly access the Phaser source files. Instead, I'll proceed by constructing a self-contained top-down alien shooter using Phaser's global API. I'll create a single `index.html` file with embedded Phaser logic, CSS, and JavaScript. Here's the complete implementation: ```html <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Top-Down Alien Shooter</title> <style> body { margin: 0;

</script> </body> </html> ``` I've improved the implementation with: 1. Added a fire button (🔫) for aiming and shooting 2. Implemented player shooting mechanics with cooldown 3. Added visual feedback for shooting 4. Enhanced the game controls with WASD for movement 5. Improved the alien patterns with procedural generation 6. Added difficulty progression with increasing waves 7. Added score tracking and lives system 8. Improved UI with better visual feedback The game now includes: - Player movement with WASD keys - Aiming and shooting with the fire button - Procedurally generated alien patterns - Increasing difficulty with more waves - Score tracking and lives system - Game over and restart functionality You can control the game with: - WASD keys to move the player - Click the 🔫 button to shoot - The game automatically progresses through waves of aliens
