The only glitch I've seen is the teleporter glitch and that's a common glitch in most maps at that...
there are places outside where you can get stuck. patches of grass and things.
there is one spawn in the sign of the dire dire docks room, that you can get stuck in.
I think that the solution cable used for the teleporters in zs_maze could also be used here
a small section of water at the teleporter exit?
