Love this game and the music!
I have an idea for this game. Maybe after completing it once, we can choose from a few different kinds of balls with different physics like bounciness, etc. It would make the game worth playing a second or third time (I haven't finished yet). Another thing. I have a GTX 1080 and while I can run it at 60fps at both the gtx 1080 and gtx 970 settings, the ball seems to move way faster when I pick the 970 settings.
