So it's a roguelike of a sort. Interesting. As i understand it there's no direct goal and you're just trying to see how far you can get? Having no end goal might be demotivational to the players, so you'll have to make extra sure that the fights are enjoyable. It's doable, but i think it's a risky move to design the dungeon around that, don't you?
Well. we'll see. I can always help you coming up with new encounters, though i'm keeping the really good ideas for myself :hehe
