ranehal/game — reverse-engineered prompt

Build me a simple, polished browser game in this existing project. I don’t have a detailed spec yet, so please inspect the files and use what’s already set up. I want something fun that loads quickly, works on desktop and mobile, and feels complete enough to share with friends.

Make the game easy to understand right away, with a start screen, clear instructions, scoring, a game over state, and a way to restart without refreshing. Add clean visuals, smooth movement or animations, and responsive controls that work with keyboard and touch. Keep the design modern and not too cluttered.

Please make the code organized and easy to change later, since I may want to add more levels, enemies, or power ups after this. If anything is missing from the setup, add only what’s needed. Look up current docs online if you need to.
