I like the style of the game. It looks absolutely beautiful and vibrant. I especially like the pseudo-3D "star field" effect in the background.
I feel the game could be just a little bit faster, though. The paddle also seems a bit thick (Does the ball collide with the green band on the paddle or the whole thing?)
Also, if I'm correct, Arkanoid (or Pong, I can't remember :P) had a mechanic where if the ball would go at different angles depending on how it hits paddle. For instance, if the ball hit the paddle closer the paddle's left edge, the ball would go further to the left.
Other than that, the game looks great! Keep it up!
(By the way, what are the Japanese characters underneath the title? Is that a subtitle or just "Evolution" in Japanese?)
