commented out calls to refreshBallCountDisplay (the methods checks to see if there is a label node for displaying this count, but I’m not making one so it was just a wasted call every time a ball was created or destroyed)
make ball colour depend on fragment type again
in touchesBegan(), if we find a ball that has been touched, now we break out of the loop over the full set of balls
for ball-ball contact with vertically aligned balls, contact event is now ignored
doh
