Remix: Toxic Work Environment

Build a small, playable browser game inspired by "Toxic Work Environment" (Platformer).
Concept: You have an interview for CEO very soon, but the elevator is broken, you have to climb through 25 floors without touching the toxic sludge to get to your interview on time.
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): Space to jump, Esc/P to pause, gamepad support. Show them on a short how-to-play screen.
Players: single-player.
Core loop: include a visible score, a timer or round clock, levels, stages or waves that ramp up, an optional local high-score table, 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.
