Nice little gem. I love roguelike crawlers. Only thing I don't like about this is that I wish there was more variation in loot. Like if you could find a crossbow instead of a regular bow for the archer, one that does normal damage to 2 enemies instead of huge damage to 1 enemy, something like that. The thing I like most about roguelikes is the loot.
Anyway, 4/5, would play again (I am right now in fact).
