Implement Flashmania time-trial racing game in TypeScript

Fully implement the game described in flashmania_description.md as a browser-based TypeScript game, from an empty repository containing only the spec file.
- +0Prompt · +0Fully implement the game described in flashmania_description.md in TypeScript
- +0Agent did · +0Read the spec, scaffolded a fresh npm/tsconfig project, and wrote the core modules: types, surfaces, physics, track, audio, input, renderer, main game loop and config.
- +0Fail · +0tsc failed: PHYSICS_CONFIG was imported from the wrong module (physics.ts instead of config.ts).
- +0Agent did · +0Fixed the import path and got a clean tsc build with dist/ output for all modules.
- +0Fail · +0Tried to verify the game in a real browser via agent-browser; navigation kept failing with ERR_CONNECTION_REFUSED and no browser binary was found in the environment, so no visual test was possible.
- +0Agent did · +0Added remaining todo items: gamepad haptic feedback and a high-speed wind sound, wiring both into the game loop.
- +0Fail · +0Edits to main.ts broke the class structure (misplaced braces), causing a cascade of TypeScript syntax errors around the new haptics method and the render function body.
- +0Agent did · +0Diagnosed the misplaced closing braces, restored the class structure across several edits, and got tsc to compile cleanly again.
- +0Outcome · +0Wrote README, ran a requirements-to-code audit against the spec, and called complete_goal; final build produced 9 compiled JS modules with no build errors.
Next time I'd ask upfront whether a real browser is available in the environment, since the agent-browser testing loop was a dead end here and wasted several turns before falling back to manual code review. The self-inflicted syntax breakage while bolting on haptics/wind features was the real risk, and it recovered on its own by re-reading the file and fixing brace placement rather than me having to step in. Overall it shipped a compiling, spec-mapped implementation without any human intervention, but I never got to see it actually run.
