I've created a complete self-contained alien shooter game in a single HTML file named index.html. The game includes: - A top-down perspective with player movement using WASD or arrow keys - Mouse aiming and shooting (click to fire) - Procedurally generated aliens that spawn from different edges of the screen - Increasing difficulty with each wave (more aliens, faster movement) - Player health and score tracking - Game over state with restart functionality All graphics are procedurally generated using Phaser's drawing capabilities - no external assets are used. The game uses the provided phaser.min.js library loaded locally. The game features: - Player ship rendered as a green triangle - Colorful alien enemies with different shapes (triangle, circle, square) and colors - Yellow bullets - Particle explosions when enemies are destroyed - Smooth movement and collision detection You can play by moving with WASD/arrow keys, aiming with the mouse, and clicking to shoot. Survive as long as you can against increasingly difficult waves of aliens! The index.html file is now present and ready to use. Just open it in a browser to play.
