Writing a single self-contained index.html with Phaser, implementing a top-down alien shooter with procedural graphics, WASD movement, mouse aiming/firing, waves of aliens with increasing difficulty, health, and score: - Player: a simple colored triangle or polygon - Aliens: colored circles or polygons with some variation - Bullets: small rectangles or circles - Health and score displayed as text - Increasing waves: more aliens, faster speed or health - No external assets, no network, only phaser.min.js as script include I will build the entire code in index.html now.

I created index.html with a Phaser-based top-down alien shooter: - Player is a green triangle moving with WASD, collides with world bounds - Aim with the mouse, shoot bullets with left click - Bullets shoot toward pointer, disable on timeout or alien hit - Aliens spawn in increasing waves, move downward, damage player on impact or escape - Player health and score shown, game over stops play with message - All graphics procedurally generated with Phaser graphics — no external assets - Difficulty increases with more aliens per wave and faster, tougher aliens Open index.html in a browser to play. Let me know if you want enhancements!
