Zigzag
One-tap arcadeAbout
A ball climbs a staircase of tiles, travelling diagonally until you tap — then it turns the other way. That is the whole game. The path is generated ahead of you in short runs, so the shape is always readable but never memorised, and the speed creeps up the further you climb. Miss the path and you fall; the run ends there. Gems sit on the path itself, so collecting them never fights with surviving.
