ime Elapsed: 1 hour 36 minutesMilestone: Core Engine, Split-File Architecture, & Audio Synthesizer Up and RunningWhat Got DoneArchitectural Split: Broke the codebase cleanly out of a single monolithic file into three production-ready files (index.html, style.css, and script.js) for easier scaling and modular tweaking.Core Loop & Canvas Pipeline: Built a responsive 60 FPS HTML5 Canvas game loop using requestAnimationFrame complete with a parallax background starfield.The Combat Sandbox: Implemented player physics (WASD/Arrow keys), boundary locking, and a Thermal Overheat mechanic that locks the water cannon if you spray too recklessly.Entity System & AI: Added multi-type enemy logic (Scouts, Interceptors, Heavy Cruisers, and Sector Bosses every 5 levels) alongside procedural debris obstacles.Web Audio Synthesizer: Bypassed external .mp3 or .wav dependencies entirely by writing a native Web Audio API wrapper that dynamically generates laser fire, explosions, and power-up pickup chimes on the fly.What’s Giving Me a HeadacheHitbox Balancing: Fast-moving interceptors weaving in sine-wave patterns occasionally clip the player before the particle system can accurately register the collision frame. Tweaking the bounding box math to feel more forgiving.Thermal Tuning: Balancing heat buildup versus cooling rate so players aren’t perpetually stuck in the “overheated” state during intense level 10+ boss fights.Next Up on the RoadmapImplementing high score persistence using local storage.Adding screen-shake effects on boss impacts and heavy damage.Polishing particle bloom effects for power-up drops.
