Wow! What a polished and fun time. Very ambitious and fun to play.
I don't have much in the way of the feedback but if you wanted to take the idea further some ranged weapons and other ways to interact with enemies could add a lot of depth.
Love your art and the minimalist character design. It took me a little bit to realize that the weapons have a windup before they swing, but I rather liked the windup once I noticed it.
Awesome job!
