Its good, but it can be better. Many people have recreated the classic Pong, but you should really make it your own. Add graphics, customize the graphics, make unlockables..., have fun with it! Edge away from the black and white; you can make it neon...
Bascially, make it different from the 1000000s of Pong games out there. *note im not saying get rid of hte simple altogether, but add other stuff too..
