Tried to compensate for the ball going through the flippers occasionally. I swapped out the mesh colliders for box colliders and that seems to be working better. It does change the game play I noticed not bad or good just different. I also added animation when the ball hits the rubber slingshot. "Glossed" up the play-field a little so now you can see the ball's reflection.

I added a feature that if the ball goes out within the first 10 seconds of launch, the player can try again and keep on the same ball in play.
