A truly amazing spectacle.
It's difficult for me to fathom the amount of effort made in programming this, but I can imagine that it is far beyond the scope of my abilities. Never have I ever imagined creating a game so graphically appealing and almost-entirely-glitch-free (the ball did get stuck on a black brick once, but that's it). Wonderful.
On another note, for the longest time I didn't realize that the paddle had any vertical movement capacity (as I had my cursor over the threshold). It should probably be mentioned in your instructions that full potential of the paddle can be utilized by moving the cursor below the threshold.
Also, I would change the music.
Still, wonderful job. Top scores in vote and review for me.
