Holds up surprisingly well for the very first entry in an entirely new series (and genre?) of games. The gameplay is smooth, I love the constant upgrading of your shop as you bring back more money, and the difficulty is very well balanced.

My only real gripe with it is that you have to backtrack out of the dungeon when you find the treasure. It's really not that fun to retread your steps when you've already become so powerful that most enemies on the floors you passed don't really have much of a chance to kill you.
