good, but...
it could use some more detail. for example, making a continue button in the beginning so players don't have to sit there and wait for the game to begin. also, you might want to make the actual game play area more clear (ie., make a white border to outline the play area). the score/laser bar needs a different, more descriptive design. other than that, this game was pretty addictive, or maybe i'm just super bored :D
