Great level although it had a shortcut. After reading all comments I solved it as @gmacpro. I didn't use R and the vertical lift. But once I have seen your video it is really cool idea. Thanks!
Excellent logic level...I watched your movie and that step I did it like you but.... Spoiler when B pushes the third ball I used autopilot to cross to the last zone...is it the right way? Thanks for sharing and great job @rsa92
