Perspective is an experimental first person puzzle game.
In Perspective, the player has two modes of control: a first person camera moving in 3D space, and an avatar that is constrained to the 2D world. In order to get the 2D avatar to the goal at the end of the level, the 3D player needs to move around in 3D space to create paths for the 2D avatar.
Unlike other puzzle games that make use of 2D/3D such as Crush or Fez, Perspective allows the player to move around in 3D space freely. This opens up a lot of new ways to use perception as a puzzle mechanic to create new paths in 2D.
