"Fez" and "無限回廊" (Infinity Mirror) are two games of different genres. The former comes from Montreal, Canada, and can be considered a "side-scrolling" action game, while the latter originates from Japan and is more of a "2D" puzzle-solving game, set to release on both PSP and PS3. Though they differ in genre, their commonality lies in the fact that at first glance, they appear to be 2D games. However, during gameplay, players must utilize the transformation of 3D perspectives to find new paths or complete levels. What's even more ingenious about the latter is that it uses the planar optical illusions created by shifting three-dimensional perspectives as part of its gameplay mechanics.
