Perfect! I've created a complete top-down alien shooter game in a single HTML file. Here's what's included: ## Game Features: **Controls:** - WASD or Arrow keys to move - Mouse to aim and click to shoot **Gameplay:** - Player ship with health system (100 HP) - Waves of advancing aliens with increasing difficulty - Score tracking with wave completion bonuses - 4 different alien types: - Basic (circle with spikes) - 10 points - Fast (diamond shape) - 20 points - Tank (square) - 30 points, 3x health - Shooter (crosshair) - 25 points, shoots frequently **Power-ups:** - Health (green cross) - restores 25 HP - Shield (blue circle) - temporary invincibility - Rapid Fire (yellow) - faster shooting for 5 seconds **Visual Effects:** - Procedurally generated starfield background - Muzzle flash when shooting - Particle explosions when aliens are destroyed - Player invincibility flashing when hit - Shield visual effect (blue tint) - Smooth UI with health, score, and wave display **Difficulty Progression:** - Each wave adds more aliens - Aliens become faster and shoot more frequently - Alien health scales with wave number The game runs entirely in the browser with no external dependencies. Just open `index.html` in a browser to play!

Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
