It's good for a scratch game. The idea of multiplayer seemed fun but the limitations of scratch could not show it. If it was not some kind of personal challeenge i recommend ou to try to do this game in a cool engine like Unity. It's not really hard.

cool game, the idea of a medieval rhythm combat game just cracks me up. I feel like this idea has a lot of potential and could be really fun if developed further.

I would highly reccomend using different background music since the one you are using now is copyrighted (SunStroke Project & Olia Tira - Run Away) and because of that would break the rules of the jam. I also got no clue weather this is an online multiplayer game or if some button will magically spawn in a second player, an explanation on screen would help loads I think.
