Tipping Point

Move the goal up two levels, then put stairs on the right from level 1 to 2 and stairs on the left from levels 2 to 3 so you need to traverse across all 3 levels of balls.

@nGord No, you need zappers to be sadistic.

@B Hill Great shout. I'm tinkering with it, haven't completed it that way yet. (Not added any zappers!).
