It would be great if the difficulty scaled a bit faster. I had some trouble with food around floor 20, but then I learned to guess the placement of the stairs and stopped exploring the whole floors. I managed to get just enough drops that I could more or less just run through the floors from stairs to stairs. It would be nice if the (very nicely done) treasure rooms had some more stuff than extra gold or food. If there was a scaled equipment, I wouldn't be able to ignore exploration without getting slaughtered a few floors down.
Obviously, several extra end-game enemies or a final boss would be sweet. :)
BTW, I dig the graphics. :)
