Miegakure

Miegakure is a platform game where you explore the fourth dimension to solve puzzles. There is no trick; the game is entirely designed and programmed in 4D. Because humans can only see and move along three spatial dimensions, pressing a button allows to “swap“ one regular dimension with the fourth, invisible dimension. The protagonist can use this ability to see inside closed objects, walk through walls, move objects from one dimension to another, hide under 3D shadows of 4D objects, and more.
