Wow, really unique hole level. Was quite hard to figure out how to reach the exit, but there was no optimization needed. The 2 off(s), here!
I'll be back! :))
EDIT (the next day): Oh, there it was. And now it seems so easy. :))) Really hard structure to break into. Super tricky to optimize as well Very good puzzle! I was stuck 4 off, for quite a while. Never had the two off, just went to 152. The block manipulation here is really enjoyable.
