The top

Thanks to @delator77 for supervising the operation of the level

Very tough to rate this one. You said tricks, and there were quite a few. So I kind of have to say 4 stars, even though it really is about a 4.75 Very nice work.

As usual,fun gameplay(you are increasing the difficulty and I love it) and excellent design...That's the reason of the fifth star Thanks for sharing and very well done @Memorama 13

I still don't understand how to get to the building. I've made R drop the two balls but I can't get to the elevator. Sorry but I need your help @Memorama 13

Spoiler: Hint

B needs to get away, then click on the ladder and before it stops, click on the grass or water to enter

Spoiler: Movie

I wasn't able to see the movie because of some error so I completed the level myself. As you said, there were some tricks in the level. But still,I didn't enjoy the last part because if not cautious,B would fall from the draggables and would land back on the ground. But overall,it was a nice level.Thanks for sharing!!!

Oh, and thanks for your hint!!!!!

Nice tricky level, thanks!
