Really neat concept. I had quite a bit of fun :)
That said though, the controls often seemed a bit sluggish.
Also, it'd be nice to know somehow when my abilities are on cool-down. Whether that be through a cool-down, a greyed out icon, flashing red weapon, animation or etc
Most often I'd die not because I didn't know where my enemy was, but because I thought I could kill them but my strike wouldn't come out. Sometimes it felt like my basic Z Attack wouldn't work at all if I tried to use it twice in row, or I died when I thought I wasn't in my "Recovery" state anymore, so some sort of more distinct visual feedback like a unique "tired" animation for that would be really nice.
It's understandable if you're done with the game. Getting something finished is better than trying to make it "perfect". But if you improve the flow of combat, making it more fluid and tightening controls. This could be an amazing hack-and-slash. Great job :D
