Fun idea, good graphics and a good art style.
Music also helps build the atmosphere.
Gameplay could be explained better, and feedback to the player could be more obvious as well.

I like the dungeon crawling aspect of the game, but I would suggest allowing faster movement / faster movement when enemies are not around. This would have made the navigation feel a bit better and more fluid. I was a bit confused at the gameplay because I got stuck at an enemy and nothing was working control wise (attacking or running). Overall, this is a good foundation!
