How do I get out of the catacombs?


Hint 1 of 5:
They're hard to map, since they change from game to game.

Hint 2 of 5:
I think it works like this. The first time you go through the catacombs, any
sequence of eighteen moves will get you back to 'Y2?'. That sequence
determines the layout of the catacombs.
