Got to 72 :)
I love when I find games with a cappella soundtracks in this jam and yours is really well done! The concept is simple and fun and it feels well balanced.
At first, I had trouble starting the game: When I selected the first color with my mouse, pressing enter to start the game/continue with the tutorial didn't work anymore. Not sure if it's just me, but I was able to reload and start the game by only using my keyboard. I'm using chrome if that helps.
Nice job!
