Linebreak
You draw it. They ride it.
01 About
A physics sketchbook. Draw a track, press Ride, and a rider on a board goes wherever gravity and your line send them — no steering, no saving them. Twelve levels with a limited supply of ink and a flag to reach, then a sandbox with no limits at all, a timeline you can scrub back and forth, and a Share button that packs your whole track into a link.
02 How to play
Draw with the pencil or the line tool, then press Ride (or Space). Land on slopes, not flats: a hard landing, a sharp kink at speed or a knock to the head and the rider bails. Orange boost lines shove the rider the way you drew them, cyan springs throw them off. A star for the flag, one for every pip, one for staying under par on ink. One finger draws, two fingers move and zoom.
03 Development status
Beta. A run plays out the same way every time, on every device, so a shared track is the same ride for whoever opens it. Nothing is uploaded: the track lives in the link. Make something daft and send it to me.
