Your right, kinda crap.
I'd like to say it has potential, but it doesn't. Here is what is wrong:
1) Paddles are too slow.
2) What is with the ball phasing in and out?
3) Nothing innovative about the game whatsoever.
4) Can't see player score when it's zero. Scores don't reset when you play again.
5) Didn't really notice any difference in difficulty (Medium seemed easier than easy).
6) Poor overall graphics.
My advice, if you are going to make something put some effort into it or don't bother.
