A nice level. Initially I was going the wrong way so many steps off, changed direction and got it to 2 off, a few attempts were then required to get to 54 steps.
2 tries for me (was straight 2 off on first try). The key for me was to notice before to start, how much could consume a back and forth between start and target on one side... From there, the configuration of the blocks around target told me the rest. :D
