Lovely rhythm game. It took me some time to realize that I didn't have to act on every beat, just had to time my actions to the beat. After that it was smooth sailing to the finish line.
I had the same issue as the poster below, where I managed to get up high on platforms but wasn't able to make the jump at the top. After respawning the platforms were gone, but there was a path down below that I could take instead (maybe this was even the intended path?)
As for improvements the track could be made more interesting while keeping the same beat, but then you do need a musician on your team ;P
Great job and Congrats to the whole team !
