I like the concept (reminds me of Arkanoid and similar games from back in the day) but it just jumped right in there didn't it? Try a count down or something (3, 2, 1, GO!) cause I automatically lost a life without seeing the ball before it was too late. Also, I found that after you click "Play" to start (cause it's still under judgement) you have to click again before you can even move with the arrow keys. Add a preloader/playbutton and that should fix the problem.
2/5 (cause the insta-death, no opening, no sound)
7/10 Nostalgia (would have been 10 except the reasons above)
Work on it to make it more awesome and resubmit as "new and improved".. lol
