Its suprising how open ended the levels can be. I had a similar "cheating" experience on the first double bonding level. I was having a lot of trouble with it initially (oh, you can move the start points?) until I finally got it. I had a straight line for the red waldo trail (two-way), and noticed while doing it that the red would get caught up on the sync on the way back until the blue had done another full circuit of the board.....empty handed because the input switch was on the red waldo's trail. It worked, it just was no where near efficient.
