This was fun! I found myself wanting to keep playing 'til I had beat the AI in all the events at least once. I liked the audio design, particularly the rocket event sound effect. I liked the little hints toward what the events did with the sprites. Though I never figured out what this event did:
I didn't notice any difference between it and normal play.
Edit: Huh, that sprite shows up when I edit the comment, but not when I post it. It seems to be a picture of the paddle and the square ball's trajectory off the top of it.
