I just tried out the demo. I was using a controller and I think my only real issue was that you throw out a lot of information with those tutorial pop ups that don't ever seem very relevant. A lot of the stuff that requires the combo meter never really came up and your game uses a lot of buttons that all essentially do the same thing.
Other than that, everything else look pretty solid, except against the boss. The lizard guy that tries to eat you. Somehow after breaking free I got launched into the sky and never came down.
