The animations look fantastic, and the gameplay is intuitive enough. My only concern is that it can feel a little floaty at times.
I'm not sure what else to say because a game like this requires other people to play against to truly apreciate, I don't think playing the AI is enough if every character is essentially the same.
However, I think you could make a compelling gauntlet mode if you added some upgrades, new stages and forced the player to unlock skills along the way, as dumb as it sounds.
Keep up the good work.
