Well, even in the video the framerate seems kinda low, so that could use some optimization. Some of the animations look a bit stiff (when this character enters the match in the opening cutscene they sorta hover in standing perfectly upright with no sign of momentum). The voice acting is hard for me to make a call on since it's in a language I don't speak, but when they get hurt they more like they're bored than in pain. And finally, the lighting is too dark and doesn't have much contrast. Even in the map where they're outside the characters are very shadowy.

But like, I get that since this is still in development these things can all be worked on down the road.
