Contrast

Great one! It looks like a 2x1 level...
First you have a knot and then a typical mekorama construction, both of them with interesting steps and tricks.
By the way, I really liked the step to get B down to the grass in left side of the level.
Thanks!

What @chemi said. Really. Including liking that B-drop step.

Also, very smart how you prevented otherwise possible shortcuts.

Classic game of two halves. The metal half looks intricate i thought it would do more than it actually did. Still it was a nice couple of moves for B. Spent about as much time figuring out how to drop B in the stone half. Nice to watch the rest of the level play out.

Lord have mercy! I DON'T know what the heck I'm doing!

Would you prefer a hint or a solution video? I was planning to wait a few days to post a solution video to give people a chance to solve it without hints first.

@kathryn rogers you're not alone
I got the metal half, that one was pretty easy, but the stone half...

Spoiler: stone half

I can get R to the motor part, but then i get stuck. Getting another R on the gras is easy too, but he doesnt get anything done there

@Sculron You're really close!

Spoiler: Next step

B needs to follow R to push the second ball, then R can climb to the win. But how can B cross the stairs that only R can cross?

@Star Penguin video I guess please?

@kathryn rogers Hints and solution video have been uploaded to the caption.

Dang that was tricky! But fun!

I still have not managed to solve it. I do not want to use the video help . I like the intellectual challenge. But if I reach into deadlock, I might give up

@hadi There are two hints also on the captions page if you haven't seen them yet.

Tricky.
I watched the first few seconds of the movie, and then it came to me... i always started with the metal part, that's why i couldn't find the, solution.

Honestly, this time, like the previous level you designed(scuba), I could find 80% of the solution, but I could not solve the solution that put B on R. I finally had to go to the inside of the caption for guidance.. Of course, my method in Raise the first R, would be easier and faster (without using B)

@hadi Glad you solved it at last! There are many ways to put B on R; I like to use different methods for variety. Also if I only ever used one method, then my puzzles would be predictable and easy.
