Description from the developer
Duotrace is a chill but sneaky-tricky puzzle game. The rule is simple: trace every line in the shape exactly twice without lifting your finger. Sounds easy, until the shapes get tangled and you have to think ahead to find the path that works. What sets it apart is that double-trace twist. A small rule that becomes a real brain teaser, with a great "aha, got it!" feeling once you crack a level.
