The half a star is for a fun and colorful design. On any other aspect, the game is a disaster.
The sounds are annoying, game lags, has a major bug (ball passes sometimes through the pad) and it is just a copy.

Please dont upload copies of games onto this website. This would be a cool thing to put in the Dumping Grounds so you could show it to your friends, but this is not what should be put up on Newgrounds. Make your own adaptation of the game, give it some variety, only then will it be considered your game, and not just a copy.

Well. It's definitely pong. But more colorful.

This shouldn't be posted in the tutorial section. It should only be posted in the tutorial section if other people learn from it. Also it would be wiser not to submit make simple games just made for the sake of learning.
Also the Pong Clone was mildly entertaining, but it lagged a bit on my computer. Although it could have been my computer, it would be a smart idea to optimize your code, if you haven't already.

classic pong. great and simple gameplay
