Spoiler: The balls and the path

Here is a picture of the balls. The order you get to them is the order you're supposed to walk

But between the 2nd and the 3rd one you've got to join the left part (on this picture orientation) and find a way to walk to the right part. Courage! I know you can do it

@TR O No... Sorry to hear that... I'm gonna write on MP as this is too sad

@TR O Now that I look back at it (especially after utilizing the mechanism in my newer levels), I think a stable "jammed machine" mechanism actually requires at least two movable blocks to jam the slider / motor -- so you first need a secondary slider block to stop the primary object from moving, then another free block (i.e. detached motor) to jam that secondary slider (you can see it clearly in @richardfu_ 's Limbo). This would create a chain of jammed sliders that would unlock in a sequence when a ball is pushed inside. Although it also works with just one direct free block as the obstacle, the extra slider block in between would actually minimize the chances it might trigger itself due to stochastic vibrations (and would make the level much quieter too ).

Still, this is one of the best "colossal" levels I've ever played! More people should've given it a try

Thanks @chemi! It is better late than never.

For those who had so many difficulties with that one and persevered till the end

Thanks @Skitmo ! Merci l'ami
