Indie developer Ko-Op Mode has started teasing its next game, a wacky puzzle affair called Gnah! It focuses on navigating through the insides of illustrated heads (called Gnahs), each with its own decorations or mechanisms to fiddle with. It's due for PC, Mac, and Linux later this year.

The trailer on the official site (via Rock Paper Shotgun) shows off the unique art style, but we haven't seen a puzzle in action yet. It's an interesting hook if nothing else, though, and the method by which Ko-Op is rendering the 2D illustrations into a 3D model makes them look nicely inventive. Check out the teaser below.
