I love the concept of a musical fighting game. Also your player character has to be the most badass looking character of all the jam entries. He looks so cool. And your title screen looks so damn awesome. The fact that your title itself can be played around with with the mouse makes it really stand out.
Talking about the gameplay, it is kind of slow for my taste. I can't complain because you intended it to be as it is. But I think it could have been improved. And I found the timing to deflect attacks to be too precise. Also more game juice could have been added here to improve the game feel. The spellings and grammar are wrong at many places and I don't think it was intentional in a funny way. I know that's not part of the gameplay but it is part of the game and it bothers me. But I suppose English isn't your first language. It is not my first language as well so I can understand.
And by the way, you are using mouse position in your menus and also to exit the game. Shouldn't that count as more than two controls. I'm not sure. I guess the judges will decide. But in my frank opinion, it disqualifies you.
Good game. Could have been better I think, maybe if you had more time.
