Great game honestly! I died on the 22nd floor as the knight. I do not understand how I am supposed to get rid of the Weakness effect whenever I get, as that would disable the usage of my knife, which could have come in clutch numerous times. Eventually died to a noise trap activating very buffed enemies. I dig the artwork a lot!
IMO enemies should be dealing you damage when you USE the key, but NOT when you exit. It's the same thing, just that I think this makes more sense. Or if you don't like that, you could make one of the next classes be immune to damage when you exit a level!
