Firstly Congratulation! The game is good and catchy!
I kinda wanna give some advices for future work! Usually dev use what we call Juiciness to make there game really catchy (You can see some talk about it if you search for the term) Basically it's small element to make part of the game more polished:
For example: You can bump the score counter or misses when it increase (You increase the scale of the score and decrease it just after) It will also make add to the rythm to the music!
Adding info for the player to know how well he was in rythm can also be a plus!
But for a gamejam game, it is already really great and you are in the good way for it!
Again Congrats!
