The whole idea of not knowing what an item actually does until you use it works really well with the jam theme — every new piece of loot makes you question whether you should even touch it I also really liked the music and the minimap, they add a surprising amount to the overall feel of the game.
The game did get pretty noticeably laggy for me at times, especially during combat. If the performance gets a little more polish, I think the whole experience would feel much better. But the core dungeon crawler idea is really fun!
