I think my favorite thing about this game is that it's a great example of scoping appropriately for a jam. You focused on one fun mechanic and did so much with it, and still had plenty of time to make great visuals and add appropriate audio to enhance the experience.
I'm not colorblind, but I do have very reduced vision, so differentiating blue, cyan, and purple was a bit difficult for me at times, but it was hugely helpful that all colors had different sound cues.
Great entry and best of luck in the round!
