I really love the logic of the geometry of the turning stairs! There was an active builder on the forum recently - @BlueDragon. He did levels without tricks. And he often used revolving ladders. Nowadays, almost no one makes such levels. I am very glad that you have made such a level. I love it. From me 5!
Not exceptionally difficult, but exceptionally clever & fun. B has quite a geometric adventure in this one. Nice job!
