In early 2012 Digipen student Logan Fieth created a 2D puzzle game called The Fourth Wall. It used the longstanding "wrap-around" effect - in which walking through one edge of the screen repositions you on the opposite side ala Asteroids or Towerfall - as the basis for its brainteasing as players were able to shift the camera around, dictating the level's geometry based on which borders were visible.
For example, you could get past a wall in the center of the screen by locking the camera such that you would walk through the west side, then appear on the east end. From there, you could unlock the camera to pan alongside you, as demonstrated in the gif below.
Now, Fieth and his studio, Ludo Land, have set up a Kickstarter
