Got to around 2:15, don't know how many songs are there but this would probably be it. The game is an interesting combination of a rhythm game, a bullet hell game and a reaction game. The idea is quite unique on its own and deserves some kudos. The music and songs are very nice too, and I guess that probably used you quite a lot of time in this jam.
As for some criticism coming from both a music game player and a bullet hell player, I'd say the game is difficult (but not in a good way) from time to time, where along with the music, the bullets are coming in quite fast and jam-packed, like for example the drum track in the middle it's almost impossible to jump through or walk through without talking any damages. It doesn't help especially when the input controls are quite unresponsive at times. There are quite some instances where the space button doesn't register correctly, and I do take quite some damage because of that. It also doesn't get the benefit of being a rhythm game, where the beat itself is a guiding factor, in this game you are supposed to dodge them instead. So most actions will be off-beat inputs, and really make the game less like a rhythm instead.
Anyway, I think still you did a nice job. Rhythm is always hard to do and even harder to escalate from. I think you all did a nice job!
