Not too bad, not too good either.
The preloading-screen was annoying, and it seemed when the squares stopped that the loading also stopped. You could instead of that screen have a plain black screen, maybe with a few twinkling stars to give the feeling of an outer-space game.
The gameplay was good, realistic with the panets which disturbed the ball, and pretty good graphichs. Nice sound.
Pretty good. Not too good though.
