Thank you for the thorough feedback! I agree with mostly everything you said.
The weapons were tweaked to give some semblance of progression, but everything except the sword and hammer is pretty much OP. The rooms are also supposed to scale in accordance with your gear (bigger/more enemies) but this was just thrown together and not play-tested and adjusted.
Again, thank you for playing through a good chunk of the game :-) . Your feedback is really valuable!
