I tried to treat this kindly because you said it was your first game, but it really needs some work. Obviously there's very little practicality to this unless you have another person with you, so I'd recommend building in an AI opponent. If you had done that I would have scored you much higher.

Sound effects are a bit harsh on the ears. Considering they happen so often perhaps try something softer next time. Can't really judge the visuals as it's just a simple pong game made of a few pixels.

Best of luck in the future.
