My gameplay was identical. Liked the change in thinking that helped me see the gameplay. Not what does the ...... ..... enable but what does it disable. Best red herring i have seen for a while. Spoiler: Red herring pillar L turning towards centre from the draggable then turns to face left and freezes allowing B to push the ball and low ceiling across to get B up top before the route gets blocked.
I didn't get the star beside the trench because my Pillar L won't come out after. Then I watched your video and your PillarL wasn't stuck there. I didn't notice the red herring @ridgerunner mentioned and thought it was a trap.
Spoiler I had to see the video for your move (you managed very well the L into the machine along with the Ball.) I quite struggled on that part. I made the right moves on my first try, but in wrong order. I made it right order, when I realised Ball stopped while L was engaged into machine. Superb small space level!
Never would have thought to put pillar up in that space so thank you for the VS. Very tricky level in a compact space
