About
Draw one line from the dot to the ring. It is mirrored down the middle as you draw — and the obstacles on the two halves are never the same.
So one stroke has to answer two questions at once. The path your hand takes has to clear the walls you can see, and its reflection has to clear the walls waiting on the other side. Sometimes you have to hug the far edge for no reason you can see, purely to save the mirror.
When you get it, your line and its reflection close into a single symmetric figure. Because the stroke is freehand, no two are ever the same — the ink even thickens where your hand slowed and thins where it hurried. Every one you make is kept in a gallery, and you can share any of them as an image.
100 levels, easy to hard. Fail as often as you like: there is no timer, no lives, no waiting. The line clears and you draw again.

August 11, 2026
All 95 generated levels rebuilt to be sharper and far more demanding: tighter corridors, more moments where both halves of the screen squeeze the line at once, and a difficulty curve that starts sooner and climbs higher. Every level is still machine-proved to leave room for a human hand.
