Mountain roll

This is a big level with some logic steps and hidden elements. It might require some exploring, and may look confusing at first. The level does not require the use of any tricks. If you have trouble with hidden elements, look for red bricks: they will help you figure out the hidden elements of the level.

Thanks to @ridgerunner, @cimarronline, and @R 'oland for playing the previous version and leaving their feedback. Additional thanks to @cimarronline for pointing out a major unintended solution and to @ridgerunner for finding a minor unintended path.

Spoiler: Changes to the level

- Fix of a major unintended solution that @cimarronline showed.
- Fix of a minor problem. Previously, the choice of sides was useless for one of the balls, as was shown by @ridgerunner in the video of his solution.
- Some minor design/esthetic changes.

Spoiler: Hints

- red bricks on the walls indicate the paths of the balls that you push outside the cave.
- after you push the ball at the right corner of the cave a mechanism will activate. It will block one path, but also open an another one.
- metal half-pillars that are dropped by half of a block can make B descend down one block, but it's one-way. The metal half-pillar near the start will help you understand how they work.

Really not helpful to delete the old card, I was not not able to read the other comments. Also I'm curious about the changes.

@R 'oland, I apologize for that. I edited my comment so that it includes all of the changes I have made.

@cimarronline
I don't think so, I used no tricks at all. But no matter who found a shortcut; Why is it necessary to delete a card then?

This annoys me..

@R 'oland
Edit: I will delete the previous versions of my levels as I usually do, but now I will leave a link to the previous versions in the info comment under the newest version. This way, anyone who is curious about the changes to the level will be able to see them.

Fun! I especially like...

Spoiler

the partially sunken half column near the top. I didn't know they could be used as steps down. Without having that in the path to learn from, I'm not sure I would have noticed the solution.

After a while I just realized the position of the half pillar slightly down
It's a complicated design, but amazing. Red herring that made me think for a moment. This is so much fun, thanks for sharing.

@MekaSage, @Labyrenight, Thank you for your feedback! I'm glad you enjoyed the level.

Nice design and fun gameplay.

This is a very confusing and interesting level !! He certainly deserves a 5.
But I wondered for a very long time how to get to the other side. The whole problem was - in the slightly omitted blocks !! I could not imagine that it was possible to go down from them !!! I have never met this. It was always obvious to me that it was impossible to descend from such a block. And yet - it is very hard to see that they are slightly lowered. If it could be seen better - I would have guessed faster))) !. I read the comments and realized that everyone had a problem with this))).
But if you do not take into account the problem with these blocks - the level is very steep !!! Thanks.

@Denis Nazin, Sorry if figuring out how these blocks work was too troublesome. I should have added a hint about them from the start; the hints now have a demo and an explanation, so that you can replicate this effect )

As the previous version, my favourite level recently released.

To me, the previous version was just fine with the top ball, just a red herring.

Thanks for sharing this great level
