If you're looking for an Xbox One exclusive that will stimulate your brain, then look no further. Factotum 90 will make you feel smarter than you were before playing which is just about the best praise you can give a puzzle game. While you won't have any monumental breakthroughs like in Fez or The Witness, the small victories in each of the game's 30 stages are still extremely satisfying. Small annoyances slightly mar the experience, but this is one brain teaser worth checking out.
