Very solid entry! It's a ton of fun, Love the 3d four color aesthetic, and the sounds fit quite well. The punch animation doesn't feel weighty for what it's doing though.
It's pretty tough to tell if you're gonna hit the ball or not, especially when it bounces up. I feel like some kind of indicator would be great for that, like a shadow of some kind. An indicator for when you've charged up a punch enough to hit would also be great.
I think the back wall health also needs to be a bit more obvious, since I didn't even notice it the first time I played.
Overall, it's a pretty great game!
