I really enjoyed this.
The AI only jumps when the ball is too close for him to react, which makes it impossible for him to get it if it goes too high.
I would feel more in control if you automatically feel through the platforms when holding L instead of there being a delay between you hitting the platform and falling through again.
But overall, this is one of the most fun games I've played in the jam.
The floor collision is a bit janky.
