Not bad, but still same old Pong.
Pong games are all over Newgrounds, but yours is rather well done. The similarly themed music was really well put together and well chosen. I would recommend putting multiple music options into the actual game, like having a few tracks to choose between while playing. Not saying the one there is bad at all, but it would be nice to have some choice.
I will give some praise to the gameplay itself though - the controls were responsive, and the CPU paddle actually had some sort of AI running it. Most Pong games here just have the paddle going back and forth in a premade pattern, just tweening back and forth. Yours actually acted on it's own, which was rather nice.
A good version of Pong, but still just Pong. Hope to see you improve in the future!
