@Meko Guy I just checked the video as I had forgotten about the gameplay. Pillar L can help B to get to the grass strip there. A fall might be useful for B.
@masterifu - I got it so after I do some yard work, I'll put the plan in action and see if it all works. The auto pilot under the lift is easier than having B fall from the rotor.... EDIT - Your comment was there while I typed the above comment - I got it without help but thanks for the hint.
I really didn't think I was going to finish this level as the opening didn't seem to work very well. Spoiler: First Attempt the ball stayed, released L and the tap wasn't hard enough Spoiler: 2nd Attempt the ball stayed, released L and the tap was good, went to release L and B hit the other ball by mistake and it missed Spoiler: 3rd Attempt the ball rolled off before B got back Spoiler: 4th Attempt the ball stayed, released L, tap good, B hit next ball properly, didn't raise the lift as the ball past , B nudged the ball but the ball didn't hit the wedge well to roll far enough I stopped and typed this up - to relax before proceeding... Restarted and take my time at the start and all is good. Dropped my guard and L gets trapped after the ball release section on the way to the next star.... My game play for the next star/ball didn't include a ball. Your method was cleaner but I got L and B in and out safely. After that it was clear sailing to the win so I thought. B entered the spinning rotor and fell the wrong way but the rotor did raise B up - thank god. Nice level - I did enjoy figuring it out. Thanks for sharing
