Very cool! Impressive visuals, especially given the time frame. While the gameplay was pretty solid, the sound design left me a bit wanting; given the musical theme, it feels like there should be more audible feedback to the player's actions, as well as things like the boss winding up attacks and such. I also found that in general, there was no real impetus to switch modes, and I remained in green mode most of the time. I appreciate the nod to musical modes! I'd love to see how you all improve this down the line, there's a lot of potential here. Great work!
