Nice puzzle, though not difficult. It can be won with both B and R, though it's obvious R is intended. That solution is also cleaner. For B two falling autopilots are required. Since a third is already part of the intended solution, I'd call it an official alternative, as we can't argue it's a no-trick level. The level also looks nice, so well done.
One hard move (that I got on both attempts). Nice clean level - thanks Edit - forgot to mention that I didn't use much of the lift mechanism where R is. Spoiler other than to lower R
Very nice logic level although little bit easy. I liked the simplicity of the visual design and the well designed path. Thanks!
Not difficult but a nice contribution between B and R with some interesting balls path at the begining. Thanks!
