Tightrope walker

The level is small because it's a demo of a long bug. I deliberately made the rail long, because when the radius increases, the bug becomes much more significant!
The trick is not difficult, you need patience !!

I discovered this effect (bug) when I was testing my previous "Spin Smile" level. With this bug (trick) you can pass my previous level much easier

The minimum amount of lifting the rail is 4 times. I would be glad if you get less, but in my opinion this is unrealistic. Good luck!

I used this technique in your O-O-O-What? level to move B slowly over all sides of the handle. That way I could reach the middle much sooner. I left a comment on the level page and showed a screenshot (below) as I found a bug where B then couldn't move!

Spoiler: screenshot

Hahaha... Cool... Needed four times... Will try to do it in three...

...
cool demo level.
i think its an old method, called as pivot
where B's leg then will be sticky to higher slope.
but you exploit this method in a new way
using a tall pole...

Very cool demo thanks for the discovery my friend

@Chris Hester
your B in ur screenshoot cant move
because, its position is standing outside
16 x 16 area of map size.
i cant explain further with words
but here is another example
to demonstrate about how it is occur

Spoiler: 16 x 17

in this demo level,
where B is at 17th vertical.
it can step on any obstacles.
it should also apply for 17th horizontally.

No design,but because you often play my cards,4 for you

@Denis Nazin i also lift the rail 4 times i try to do less but i can't do that

@Ray Aznable then how to complete @Denis Nazin 's level? I watched his video and thought B was in the right place.

@BLR I manage to get to the FD in 3 rail rises But you can only get to the star in 4!

@Denis Nazin yes that's the problem

...
@Chris Hester
i solved it the same as shown in video

Spoiler: pic

but, upss
i sliped the rotater, ended up B stumbled too far

and about my previous comment,
i sent u an example using other level card,
to respond the screenshoot that u sent
in ur previous comment,
that mentioning your B stuck, can tap anywhere
when standing on outside 16 × 16 area.

Already know this trick but I dont know if it works on slider rails too. New experience for me. Thanks for the demo.

@anomalli Thank you very much my friend!

Friends, I think I understand the physics of the trick! Here is a photo demo:
This can be called "Static Autopilot". B tends to occupy the cell from which it is displaced by external forces. Freezing the slider and the motor is much stronger than B's urge to return to the starting point. But when we move very slowly and with a lot of leverage, the priority of the dominant force changes. The freeze loses its power and B's desire to take the starting position becomes the dominant force - B moves towards its starting point!
