Thank you very much for your comments. I have noticed the "Game Over" bug after posting the game ( and fixed it ). I will try your suggestions ... Thanks a lot...:)

Really cool idea! Here are just a few things I noticed. - The text in "How to Play" is difficult to read -- you might try a lighter color, or a darker background. - There's a bug where after you get GameOver, you can't Start Game again. - The paddle is a bit difficult to see. It's small, and the green foggyness hides it especially when on the far left or right. - Using mouse is fine, but the keys seem to be physics based, adding an acceleration that doesn't feel natural. (I suggest always moving the paddle without physics.) - Have you tried isometric camera with this? I'd like to see a higher (but still angled) camera angle and isometric mode.
