Any puzzle you can't figure out, probably leads back to DWB. From day one the crypt puzzles were, well... cryptic! Made no sense. No clues or anything. And the crypt was suppse to be the easy level. Atleast my Shrine light-shaft puzzle still made it into the game
The crypt was originally TWICE the size it is now. There was this whole other section to the far east that was a catacomb of sorts which ended in this huge vaulted (church like) room. The original crypt was very old-school DOS mazes, but 3D.
