Good to see that you guys could create such a nice game together! Playing your game feels very nice. The qraphics look very well done and harmonize well with the audio. I like the individual look of the levels. Maybe you could add more variance to the gameplay in future releases.
I don't know if I just missed it, but for a full release I suggest the game to have some more UI Elements like a Game Over Screen or ways to pause, restart and quit the game from within the game. I think that would round up the already good game a little.
Good luck to you guys and I hope the jam inspired you as a team :)
