We first mentioned this game about a year ago, and it was released in the interim at some point:
levelHead uses a hand-held solid-plastic cube as its only interface. On-screen it appears each face of the cube contains a little room, each of which are logically connected by doors.
In one of these rooms is a character. By tilting the cube the player directs this character from room to room in an effort to find the exit.
The game was developed with open source tools on/for Linux such as Blender.
