I played it a few times. I can't really give many critiques considering that I have absolutely no development experience, but I do have one tip: Do something about the placing of the score. Every single time I died was caused by the paddle blending in with the score-count. Every single time. I think the easiest solution would be to move the score and life count up a bit so that they don't overlap with the paddle. Either that or possibly put the paddle in the foreground so that it moves in front of the score instead of behind it.
Other than that, nicely done. I can't say that it's original, but I don't really need to point that out. The sprites would benefit from an overhaul, but that's not really important. I enjoyed it.
