It's a fun game to play and I appreciate the effort that you put in. There were moments where the music synced with the balls hitting the bricks and it felt so good. However if you wanna add something, I suggest some kind of power up like a beam or something that can shoot straight up ahead because at the end of each section there are times that you are left with one ball and small a brick that is really hard to hit, and it really slows the pace of the game which I don't think is exactly ideal.
anyway, good job and looking forward to watch you develop next.
