How to play

Stand (or sit) so your head and shoulders are in frame. The game first calibrates your neutral position for ~2.5 seconds — stand centered and still. Then obstacles start closing in:

walls — two of the three lanes flood red; lean your upper body into the lane marked safe before the wall lands.
bars — the top half floods red with a DUCK ↓ warning; squat or crouch so your head drops below your calibrated height.

Obstacles arrive every 2.4 seconds at first and accelerate to a brisk 1.2-second cadence. Three hits end the run. Leaving the frame counts as a hit — no hiding from cardio.

Privacy

The camera turns on only after you click start, and the light goes off the moment you hit stop camera or leave the page. Frames are processed by a WASM model served from this site — nothing is uploaded, no account, no tracking of any kind on your input. Verify it yourself: open DevTools → Network while playing and watch nothing leave.

Requirements

A webcam, room to lean and squat, and a reasonably recent browser (Chrome, Edge, Firefox, Safari 16+). The tracker prefers your GPU and falls back to CPU. First load fetches ~16 MB of model + WASM once, then it's cached.
