I think maybe the prob is I have jumped way ahead in the game? I somehow made it to the cathedral with out do very much in the game. It took MANY tries, but I made it to the 2nd level of the vault under the cathedral, but when I try to go to level 3, the game crashes. After briefly looking at a walkthrough, I noticed that this is the end of the game??? I've hardly done anything. I wonder if that's why it's crashing. I haven't even gotten the water thing for vault 13.
BTW, this game is so addicting for some reason! I think it's cause it kinda reminds me of play dungeons & dragons on my C64 25 years ago!
