Haven't finished it yet in the intended way, so won't rate yet. But it seems like a great puzzle. There are couple of shortcuts. Spoiler: shortcuts Some "lifts" go all the way down, which means you can autopilot on them directly from the ground. If you raise the whole thing straighaway such that R gets on a draggable, and then raise it 1 more block when R is on the draggable (with a bit of force), R walks to the win.
@Block builder You are right, maybe I will edit this level because some mistakes, and I will remove the R... Thank you for telling me about this, I will repost this level soon...
