The pixel art is pretty nice, although a lot of it is hurt because it's inconsistently scaled sometimes but the dungeon crawling is also entertaining. I like the UI design, although it might've been a bit to try and polish up. There's little feedback in the combat system other than the messages which doesn't make it very fun to fight things (I honestly didn't really noticed I had "died" since you are functionally immortal.)
Seems like a good idea, but it's not filled in enough!
