I couldn't get to the exit for a few weeks as I can't read this type of level well. I did think I knew how to finally approach it though and the approximate route. Then finally today I solved it, mainly by persistence.
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.
Luckily I missed the 2 offs. It took several goes to find the path after an initial feeling I wouldn't get it and it felt straight forward hence only 4 stars.
I finished at 2off, but convinced myself I'd solved it, assuming it was easier than it was. Once I realised my mistake I repeated the moves and saw an alternative and then got it, nice level, trickier than it may seem.
