Lots of decision making in the central section of the puzzle. I original made the wrong choice and paid a few steps for it. My first stepcount was 300+, cause I fell for ''the trick''. :))) Some obviously broken sections, but still has an optimal 2 off! :)) I was on the right track, all along, but was doing one part wrong (if that was possible, it would be even faster, LOL). Really great find, David!
