Duotrace

Duotrace is a chill yet sneakily tricky line puzzle built on one simple rule: trace every line of the shape exactly twice without lifting your finger. It sounds easy until the shapes get tangled and you need to think several steps ahead. That double-trace twist turns each level into a real brain teaser with a rewarding moment when it clicks.
