About this game

ONCE is a minimalist puzzle game built around a single rule:

Draw one continuous line and trace every segment exactly once.

Lift your finger? Fail.
Trace a segment twice? Fail.
Miss even one line? Fail.

Just you and the maze.

Draw one continuous line. Trace every segment exactly once
