Promising idea! I love the concept. Playing on keyboard doesn´t feel that well but with a controller is much better. What I don´t like is how static the player feels to control, I wanna swoosh around in a game like this and be all flashy, not stop dead in my tracks every time I swing my sword. I also have the feeling that there is some sort of really annoying distance you have to move to hit the ball, where walking ends up being too slow, but using the dash ends up overshooting because of how far it goes. I think you need to toy around with movement/attacking now and make that part feel really really good and dynamic.
