Thank you for your lessons! Like David said, it was so impossible at first
I can think of where I should put the obstacle but it was difficult to work that out Nice Shove School lesson
but how come there are 2 exits Was 2 off for quite long before. Nice design. This one is the most difficult one to me. absolutely not intuitive to me totally agree with alazeh, so difficult to cut the last 6 Finally solved this, again it might always be a good idea to come back later when you got stuck and had no ideas.
