I think the main idea is really nice. I believe one of the best ways to create games is by rethinking ideas that already exist and giving them a fresh twist.
I just have a few comments that might help.
At the beginning of the game, if neither player moves, the ball just keeps bouncing back and forth between the paddles forever. Maybe the ball should start in the center of the circle and launch in a random direction instead. That way, both players would have to move right from the start.
I also think adding an AI mode would make the game much more enjoyable. Playing against myself was pretty difficult and not very engaging.
Another thing I noticed is that it's a bit hard to predict where the ball will end up and reach it in time. Maybe the ball could start at a slower speed and gradually get faster as the match goes on. Alternatively, you could make the circle a bit larger to give players more time to react.
Overall, I think it's a really creative take on Pong. Nice job!
