That was the most ridiculous cut I've ever seen Excellent design! I like how you can piece together what needs to happen using logic. Was hopelessly 10 off and came back after months and finished pretty quickly Hard to find the exit and to optimize. Took forever I have a 4 off and a 2 off. Still can't see the 158 path. I think this is a great level (I had most troubles with finding the last 2 steps).
