The CPU just moves up and down, and when the ball passes a player or CPU it will glitch back if it is close. The music.... yeah.....

Very easy, you can just stay at the begining. Also add some music :P.

Very bare-bones. The enemy doesn't even have any A.I. past moving back and forth, so it's pretty inherently poor quality, even by pong standards.

not bad, i know pong is fun to program, maybe randomize the moves of the computer a bit more, now it is just going up and down

next time you could try adding some music to it just as an improvement
