You know how in the Psych levels you can get stuck in the spikes? That is a masking bug. You know how when you put a warp target in a masked tile you get stuck? It's a mask bug. Mask just make jazz think that there is floor under him and a roof above him, and walls to the left and right. When you are in a fully masked tile, it thinks there is a wall to the left, a wall to the right, a floor benath you and a roof above you. So, it does what it was programed to do in each of those situations. It doesn't, nor never will give you an access violation.
