Tricks used: low ceiling, autopilot.

Spoiler: Other tips

The central idea of this level is that two balls fall in the same place, but the path can be changed.
A ball has a star, it must be placed on the path where B can catch the star.
The path to victory must be filled with balls, but you have to place the draggable in the right position. A ball will be used for B to pass and then to push the winning block.
Be careful with the L and P robots, they can get locked in some places. For this not to happen, B needs to help them.
B can leave the starting area with the low ceiling trick. To resume you must use P and a ball.

Great complex adventure.

I just love levels like this. A great exploration. Must have been a lot of work. It was worth it. Thanks!

Great level took me a while but I had to keep coming back to figure it out.

Excellent level with a very nice logic gameplay behind although a couple of tricks are needed & really cool design... thanks for sharing & for the fun @Jóh always a pleasure to play your levels my Meko-friend

Wow! Quite a masterpiece I did need a look at the vs for pillars role so thank you very much for including it. But still a lot of trial and error working out the ball order and where to put B to get that beautiful star. Thank you so much for the excellent challenge

Friends. @ridgerunner , @Block builder , @Tui , @delator77 , @Sammy 5 , Thank you all for playing and rating this level so highly. You remind me that Mekorama is still worth playing.
