More Balls?

We revisted this game tonight and my gosh it's the most tedious, frustrating thing I've subjected myself to since, well, the last time we played it. It says this is for 3 year olds and up and I as a grown man can't progress to unlock all the levels. By the time you somewhat get the timing or power down, you're out of balls. It's pinpoint accuracy when I somehow miss the cup by a millimeter and I'm blowing out my rotator cuff trying to get the game to register that I'm throwing the ball.

Out of all of the games on playground, I feel like this one could have benefited from some time in the lab. Is it possible to give more balls per turn?
