Great idea, well executed. It was a little unclear to me how to progress, but with enough trial and error I was able to get some of those pesky red diamonds off the level :) The musical aspect of the game is definitely fresh.

thanks! i didn't manage to find the time to implement a wave counter or anything (its much harder when you can't just use text lol) but the waves do just ramp up over time, there isn't much progression other than that. i think i probably made it too difficult since i also didn't make much time for playtesting. thanks for playing!!
