Simple and addicting.

The game is addictng in it's simplicity. But one thing, the ball speeds up way too fast, before you can hit it4 times, it's going faster than you can see it. But other than that, yea some music background color colored ball, something to keep you attention. Good job though.

not bad

Not bad. It need something extra to it unique. Your game making skills are up to par but the game lacks originality. Maybe you may want to make levels with different backgrounds. Or make power ups and such. You could also add some music [or any other sound effect besides the ball hitting the paddle].

Hmm

I don't think the world needs another pong game

Pong...

Mmm... Another Pong game. In grey. I don´t think the world neither needs nor wants more and more pong games, which are exact copies of the original, except for example the colours.
Pong isn´t really hard to script, so what´s the point of all the pong games?

Not bad at all, but...

I would add more onto this game to make it stick out from alternative pong games.

For example, there should be around 4 to 5 difficulty level, or maybe the user should be able to edit the speed of the ball, the size of the bat, and the number of points to win the match.

Also maybe they should be able to change the colours of the ball, bat, background, and maybe even have a variety of music for the user to select.

Good luck!
