Remix: Off-G Overtime

Build a small, playable browser game inspired by "Off-G Overtime" (Action, Adventure, Simulation).
Concept: Off-G Overtime is a first-person zero-g physics sim where you drift, grapple, and haul space junk through asteroid rings while surviving solar flares, cargo-stealing UFOs, and a terrible boss who expects every delivery on time.
Tone/hook (from the game's own page): A first-person zero-g physics simulation in your browser. Drift, rotate, grapple, and haul space junk through low orbit while managing inertia, fuel, oxygen, solar flares, and a boss who docks pay for bad salvage.
Tech: use Three.js; keep it to a single page that loads instantly with no login or install.
Controls (as seen on the original's screen): mouse to aim or look, Esc/P to pause. Show them on a short how-to-play screen.
Players: single-player.
Core loop: include a timer or round clock, progress saved in localStorage.
Audio: add simple sound effects and music (start audio on the first click/tap).
Steps: 1) get the core mechanic playable with placeholder shapes, 2) add win/lose conditions and restart, 3) polish feel, visuals and sound, 4) add your own twist (setting, character or one new rule).
Make it your own: don't copy the original's name, art, text or code.
