Bang bang, bangabang bang :)
-I like what you have done with the graphics.
-All of the colours are easy on the eye.
-Bouncing the blocks you have knocked down back up to do more damage is a really nice mechanic (the effect looks nice too).
-The song has a nice novelty effect when the game begins.
-While the blocks themselves look really nice perfectly arranged in the middle - its not very functional that way. When you hit the front blocks the ball rebounds too fast because its too close and when you hit it up over the blocks there is a lot of wasted space. I would suggest raising the blocks up a bit more.
-The song loses its novelty rather quickly.
All in all I think its a really good start. Oh an by the way, I think your loading screen with the Johnny6 logo is genius.
