I've barely completed my quest for glory, dealing a final blow on an enemy while having almost no life left in me. It was a fun playthrough, though it took me about 4 tries to actually succeed. I would like a faster and more responsive movement and more feedback from my actions. I liked how you've bind actions to 1 and 2, it was very thoughtful and easy to get used to.
Overall if you add more stuff to the game it can be an interesting "dive the dungeon for a goal" crawler.
