Really fun! I love the graphics, sound, controls! It was not super obvious at first which balls were on the ground, and I felt it was too easy to block the ones in the air since it seemed to be based on a 2d collider that wasn't adjusted for a simulated 3d space. (Ie, as soon as you jump you block it even if the ball SEEMED like it was gonna still go over your head if you jump what seems to be too late.)
I would recommend ramping the difficulty as time goes on, and maybe add a crowd cheer sound when you block, and maybe a boo when the AI scores.
Overall, really fun well done entry!
