Fez Coming To PC This May, More Platforms To Come
According to creator Phil Fish, the game is coming out on Steam on May 1, with Linux and Mac versions to follow at an unspecified time. Fish says he's in talks with Sony to bring the game over to Vita, too, and it could get an Ouya port. Finally, an iOS version is also possible.
In short, if you haven't played Fez yet for some inexplicable reason, you're going to be running out of excuses real quick.
