echochrome (2008)
Echochrome is a downloadable puzzle game released by Sony, inspired by the works of M.C. Escher and based on optical illusions. Players must use five laws of perspective to join walkways, hide dangers, and create new paths to reach the echos or shadow guides in order to progress through 56 challenging levels exclusive to the PS3 version of the game. The custom level editor also allows players to create their own mind-bending levels and share them with friends.
