Vector Asteroids — Arcade Demo

Produce a complete implementation blueprint for the single-file arcade demo: game loop architecture, object/entity model, collision strategy, asteroid generation and splitting rules, saucer AI behavior, scoring/lives/waves, synthesized audio plan, visual style guide for neon vector rendering, input mapping, responsive canvas behavior, localStorage persistence plan, and a detailed acceptance checklist verifying file:// compatibility, no external assets, and no network usage.

Deliver a self-contained index.html prototype with inline HTML/CSS/JavaScript only. Includes responsive Canvas 2D setup, frame-rate-independent requestAnimationFrame loop, player ship rotation/thrust/inertia/screen-wrap, basic bullet firing, simple asteroid spawning and wrapping, collision detection, primitive scoring/HUD, title screen, restart flow, and foundational vector rendering. This milestone proves the core arcade feel and static-hosting constraints.

Expand the prototype into a complete Asteroids-style game loop. Add three asteroid sizes with jagged procedural polygon outlines, asteroid splitting, increasing waves with speed/count scaling, lives and respawn safety, extra-life thresholds, high score persistence in localStorage, pause toggle, game-over screen, optional hyperspace, and an occasional flying saucer enemy that moves across the screen and fires at the player. Deliver as a complete updated single-file index.html.

Produce a substantially polished version focused on arcade-quality presentation: glowing neon vector aesthetic, parallax starfield, screen shake, particle explosions, bullet sparks, thruster trails, flickering engine flame, subtle bloom/glow layering, tuned motion feel, Web Audio API synthesized fire/thrust/explosion/saucer sounds, optional simple beat, sound gating for browser autoplay rules, improved HUD/title/controls presentation, and keyboard-first controls with optional touch controls if feasible. Deliver as a complete updated index.html.

Deliver the final production-ready single self-contained index.html plus a concise QA report. Harden file:// behavior, remove all external dependencies, verify no fetches/imports/assets/CDNs, tune performance for common desktop browsers, handle resize/orientation changes, add defensive input/audio/localStorage handling, refine difficulty and scoring balance, clean comments and structure, and include a manual test matrix covering title, gameplay, pause, game over, high score, waves, saucer, audio unlock, and static hosting behavior.
