Knight Glitch

The Knight's Move Glitch is an obscure glitch in Microsoft's version of Chip's Challenge. In certain versions of Windows, it causes creatures with uninitialized directions to move like a knight in chess. It is the basis of the level pi or pie? in David Stolp's pi, but has also been observed in a few other levels as well. It is unknown what causes the glitch, and it is not emulated by Tile World.
