Fez has been getting good press for quite awhile now. They have recently released some gameplay footage from PAX East though, and the game just keeps looking better and better. It plays like a 2D sidescroller, BUT you can rotate the screen at 90 degree angles, like turning a box to look at a different side. You play on 2D and use the 3D rotation to solve puzzles. Just watch the gameplay trailers and you will get a good idea of how this game is going to majorly mess with our heads when they finally get around to releasing it.
