Maybe it was just broken for me, but I couldn't get any sound. I only mention it because another commenter did though, so if there wasn't any then thats okay.
I found this game extremely difficult. The difference in the momentum buildup of each of the spheres was too great and it often ended with one of them shooting off ahead uncontrollably. I really liked the concept and appreciated the graphical choice, but it was a little hard to play at times due to not really understanding what the playable areas were.
A little more time on polish would have gone a long way, but I understand that you probably didn;t have enough time due to the jam rules.
