I really like this concept. Took me a minute to figure it out, the intro is important. I did manage to lock it up trying to put a ball back down. Ended up not being able to grab anything. I think it is because I let go when the ball was half off the screen. Suggest putting the ball back for the user if they release anywhere not on the game board just store the position of the ball when they pick it up in a temp var. I will probably come back and play this again.
