Its REALLY hard, There's just sooo many things. the spawn rate for mobs is way to high, of chests it way too low. i was always out of durability on things, I could only beat it by using the really cheap strategy of tunnelling around the rooms to the end. and it is really easy to et pinned, eather by spider webs or by high knockback weapons. however, I lie the Idea, and how the rooms randomly generate, and the skeletons changing weapons but, its just hard to appreciate when your stuck in a corner with broken armor and die... for the 27th time.
