FEZ

FEZ's champion is a marshmallow-like creature named Gomez who lives in a two-dimensional world. He and his fellow villagers are ignorant of the existence of a third dimension, blithely dismissing the concept of objects like cubes as pure fantasy. However, our pixel-y protagonist acquires a new perspective on things when he dons the game's titular tasseled hat, which allows him to rotate his once flat environment by 90 degree increments. Players flip through the world's four sides at the tap of a button, revealing a bounty of hidden doors, platforms, and ledges. The catch is that the world remains flat while viewed from any one side. Platforms hovering in front of or behind the plane on which our fluffy white hero stands become flattened and part of a single plane. Trying to use words to describe this inherently visual mechanic -- which is used to create a seemingly never-ending stream of clever environmental puzzles that must be overcome in order to complete your objective of collecting scores of golden cubes -- is difficult, but the game is surprisingly intuitive when experienced firsthand.
