It's mean:
Auto pilot
Low ceiling
Hidden slider

Spoiler: Video Solution

Quite a tricky lv. It took me a while to find the slider's connection. Liked the LC that I thought I was stuck on it.

Very fun gameplay with very nice design... Thanks for sharing @Fendi

After knowing the tricks, it's quite clear for me what to do with the sliders. I like the moves at the center building where the same path is used several times but with different outcomes. I agree with @cimarronline about what he said in the spoiler.

Very tricky with the sliders affecting balls! Thanks for the VS otherwise would not have gotten this one

@Fendi
Hiya. I've tried this many times & the same prob each time. At around 1:46 in VS, the ball that's bumped is supposed to fill the space before last star, rt? Mine never rolls the distance. Can't see where it's hung up, I just know it's not working.
Aarrgghh!
Help, pls.

@MomoKeego

Yes, there is a slider move hidden there

@Fendi & @cimarronline,
I'll give it a go & let you know.

Hot dog & hallejulla! Another elusive level finished. Thank you @Fendi & @cimarronline for help with the last step. I honestly solved the whole puzzle, just couldn't get that ball placed by the win, gah. Still, feels good to ck this off my unfinished levels.
