Nice prototype for what could be a really fun game! I love melee, parry-intense, games.
If you continue development I would first look into the somewhat unintuitive controls. In the best games that are similar you simply walk in the direction you are inputting, not rotating on left and right, way too tricky and feels awkward to me.
The other thing I find important in parry games are the animations, I would go for clear start-up animations on the enemies attacks that you can visibly see and react to.
Thanks for the entry :)
