Too unstable for me...

Spoiler

The staircase that B needs to autopilot towards, also knocks B off the path as B's head bumps in to it.

Interesting move to get the ball at the edge of the level. The big penultimate move worked first time for me as did the last move. I wasn’t sure what move @Block builder was referring to. I wasn’t sure if it was required, but i moved something.

Spoiler: What i moved

I used B to raise the steeple flag rail thingy so that it toppled nto the white space.

@ridgerunner it's the very last coordinate change of B in the penultimate move, when he should....

Spoiler

move on to the stairs.

Very tricky level with nice steps... thanks for sharing @Bob Marley
Btw, as I also did not understand exactly what happened to @Block builder I made a movie of my solution so you can check it

Spoiler: My way

Ahh, @ridgerunner...

Spoiler

I thought that the fact to move or not the "flag" was irrelevant but if you do not move it, B can not reach the win block

@Block builder ..you have been unfortunate. Maybe a device thing.

@delator77 ..you just failed your demolition test! I had the same gameplay.

@delator77 it's at 1:25 in your video.

Spoiler

B bumps his head to the stairs, and gets deflected sideways, in my case.

@Block builder Ooohhh, I see... yes, maybe is a device issue

@Block builder I also double checked about 10 times and still find it stable.And I think the same@delator77 that you have a problem with your device.So according to you@Block builder Is it necessary to add a fence where you fell?

@Bob Marley That move has worked 2 out of 5 times now for me. B lands on a curved rail if it fails. If that was one block higher it would still work. Not worth a re-upload I think.

I don't have any instability issues, the last move worked fine

Since at your level you can use the autopilot, I found a very fast way to win without a single ball with one autopilot

Spoiler: My short win

tried several times, my quick way works quite stable

@Denis Nazin Oh, there it is again, a shortcut, I hate this

@Denis Nazin Um, and I thought the "slit" when you push was enough to stop the autopilot, but no

@Bob Marley In this autopilot B, a large falling column comes to the rescue. It pushes B a little. If you push the column first, and after that do the autopilot - then B gets stuck (as you say).
