Definitely haven't seen a puzzle game implement a mechanic like this before. I think, in execution, the game felt a little jarring to have these colours constantly switching, but I really like the idea you put forth. Graphics were simple but entertaining, the music actually surprised me when I realized you had it split into three parts. That was an awesome idea, though I wish I could hear it all at the same time, just with one of the parts being a bit louder than the others. Great job on the game!
