All levels unlocked.
Wrap your brain around the six sides of a cube in this disorienting puzzle game as you guide Melvin through his own mental breakdown. In a twisty 3D world where gravity is relative, Melvin must collect keys and gems to unlock increasingly confusing levels as he journeys into the darkest parts of his mind. For you that means more than 30 levels of sanity-bending platforming puzzles, and the satisfaction of helping the poor guy find himself.
