I'm surprised by how into this I got! There's no reason for first-person 2.5D melee combat to be this fun, full marks on that front. It's the super wide swing area, avoids the typical "this is a bad point-blank gun" feel of most indie melee systems.
And the deathtrap heavy dungeon approach really brought me the closest to the original Diablo's tense atmosphere but speedy pacing. My only issue is that... you probably don't need the permadeath Rogue Legacy aspect at all. Games fun in its own right. Don't think I ever came close to death. I would've liked my little fighter to be more of a Diablo 1/2 esque archetype and less Procgen McGreyMatter.
But that's probably personal bias. You've got a real fun game on your hands here, with good atmosphere, and the rest is so much fluff. And I'm the sort of dumb chuffhead that's played enough indie 2.5D fps roguelikes to be slightly sick of them. Excellent job!
