I'll go easy, because ive done the same thing
As generic and overdone this style of game is, at least you had some (untested) variable settings and working powerups. The graphics are ugly to look at for a length of time, so i would maybe ask someone else to do them for you, or maybe spending some more time on your next submission. I myself have however done a blockbreaker game and i know they are a bitch to test, but some angles the ball would go through the paddle( had the same problem) it might be a common thing.
