Fun level. One part is now slightly more difficult. Spoiler: shortcut.... yes sorry You can still climb that rotating movable you use to push B over the hole. However it's more difficult. You need te sent B from the stairs back onto the lift and quickly turn the rotating movable. It's not abvious at all, so should be ok like this.
Challenging compact level. Took me a couple of tries to get this one. Did enjoy it though. Well done as always!
