The game was a struggle with laptop not having a mouse.

could do with just a button press to separate the balls.
there seems to be some type of lag issue when a ball goes below the screen area, are you doing a find object at that point?
the first time i lost i couldn't figure out how to proceed until i stumbled on clicking the ball would start it again.
However, its nice and clean simple design and with a few fixes could be a nice little casual game, congrats on submitting it.
