bit-hatsune-miku/game — reverse-engineered prompt

I want you to turn this empty repo into a small playable game. The name makes me think of a cute retro Hatsune Miku style vibe, so please lean into that with simple pixel art, bright colors, and music game or arcade energy, but keep the scope small enough to finish in one pass.

Make it something I can open and play right away in the browser, with a title screen, clear controls, score tracking, a game over or win state, and a restart button. Use simple keyboard controls and add a little sound and visual feedback so it feels lively. If a full rhythm game is too much, a lightweight arcade game with that theme is fine.

Please set up everything needed so it runs locally with clear instructions, and add a short README telling me what the game is and how to start it. If you need to, look up current docs online and pick a simple approach that fits a tiny game project.
