Remix: Rogue Lith

Build a small, playable browser game inspired by "Rogue Lith" (Action, Shooter, Stealth).
Concept: Descent with stealth and rogue-like mechanics.
Tone/hook (from the game's own page): Rogue Lith is a Descent-inspired neon sci-fi ship crawler through hostile labs, machine vaults, and infected corridors.
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): arrow keys, mouse to aim or look, click to shoot/attack, tap on mobile. Show them on a short how-to-play screen.
Multiplayer: the original is listed as multiplayer. Start with a local or bot opponent, then add online play (e.g. WebSockets) once the core loop is fun.
Core loop: include a visible score, levels, stages or waves that ramp up, progress saved in localStorage.
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.
