On top of its lovely pixel art and sense of humour, I love how this game is all about risk vs reward by making all objects untrustworthy and the difficulty increases the further you go. Let me tell you, the enemies following you throughout floors caught me off guard.
I think my only couple of issues are that the runup feels a bit too sluggish, (especially when slightly touching objects kills your speed) and the results and cutscenes are unskippable. Also, maybe I'd put in shortcut steps that skip a few floors in case you go down too deep.
But other than that, Great job!
