Prompt for this run
Build a playable Asteroids-style game on a canvas using procedural vector graphics. Use HTML, CSS, and JavaScript as needed. Write it to `index.html` in the current working directory using your file tools. Inline your own CSS and JavaScript. Do not use external assets, CDNs, or network requests. No third-party libraries are provided. Required behavior: - Use Left/Right to rotate the ship, Up to thrust, and Space to fire. Show the controls. The ship retains momentum and wraps around every screen edge; asteroids also wrap. - Spawn moving large asteroids. A bullet hit splits a large asteroid into smaller pieces; hitting a smallest piece removes it. Hits increase the score. - Start with three lives. A ship-asteroid collision removes one life, respawns the ship, and briefly protects it from immediate repeated damage. - Clearing all asteroids starts another wave. Losing all lives shows Game Over and a Restart control that resets score, lives, and the arena. - Keep projectile lifetime bounded and prevent gameplay keys from scrolling the page. Verify: Test rotation, thrust, and firing near the initial spawn. Check that the ship changes heading, gains momentum, and emits moving projectiles. Sample the scene to inspect screen wrapping when an object crosses an edge.

I've implemented a fully playable Asteroids-style game in a single HTML file as requested. The game includes: - Ship controls (Left/Right to rotate, Up to thrust, Space to fire) - Momentum-based movement with screen wrapping - Asteroid spawning and splitting mechanics - Bullet lifetime and collision detection - Lives system with invincibility after hits - Wave progression and game over state - Score tracking and restart functionality I verified the following behaviors: - Rotation works when pressing Left/Right arrows - Thrust applies momentum when Up arrow is pressed - Bullets are fired from the ship when Space is pressed - Bullets and asteroids wrap around screen edges - Ship wraps around screen edges - Collision detection works between bullets and asteroids - Ship respawns after losing a life - Game over screen appears and restart button works The only unverified behavior is the visual appearance of the asteroids' irregular shapes and the exact timing of invincibility frames, but the core mechanics are confirmed to work. The warning about iframe sandboxing is a known browser security warning that doesn't affect game functionality. All required features are implemented and working as expected in the single self-contained HTML file.
