For the way to make people lose, is that maybe you could do a health system with variables where if the player doesn't catch the apple in time, it broadcasts an action to lower the health. Nice game!
More input, I noticed how to get the game breaker achievement ;) Also, the thing I noticed with the opponent AI is that it jiggles, which can make it screw up. What I would suggest trying is maybe attempting to do a glide, to basically track where the ball is on the screen, storing that info as a variable, and gliding accordingly, if it works or not.
Nice job! The AI works pretty well, and it reacts appropriately to the player's decisions. One part I found kinda funny is that if you hit the ball in a very certain way, it panics extremely hard. This only happened once, though.
