FEZ is an indie game developed by Phil Fish. It started devolopment in 2007 and it was finally released on XBLA in 2012 and was later ported to Steam in 2013.
The game starts off initially in 2-D, with the lead character eventually gaining a magical fez. This gives him the ability to navigate the 3-D world by rotating through four 2-D slices. There are no enemies, though there may be the stray rampant black hole. Plenty of challenges abound for Gomez, as he must gather cubes to progress further through the game.
