Just played your game but ended up getting hardlocked somehow. I think it was when I try to take over a skeleton that just died after casting ice smash. Couldn't move or anything. I think I was around 6-8 rooms in. But other than that I actually really enjoyed it!
Other feedback:
Some of the casting in combat feels a little clunky. Like casting fireballs, or the ice smash, etc... I enjoy action games that are more instant feeling like how your rogue feels. Maybe a hotkey to instant give up if you die without any bodies around so you don't have to wait. I think the shops would be better if the skill description came up on hover and then you could upgrade just by clicking the skill node.
Super fun game and idea though! I was fully prepared to beat the whole game because I was enjoying it but couldn't because of the hardlock. You've got something fun here!
