Thank you for taking the time to make the image for me! So, the "Other People Help Push" level was supposed to teach the direction mechanic, but unfortunately I'm an idiot and had such tunnel vision for the intended solution that I somehow didn't realise you could just use the pillar to block the friend's vision. :| Your puzzle is much better, thank you. I did like the idea of having to push the column back to solve it though, and I think that's still doable without the level being broken.
Hmm, I'm feeling quite tempted to make a fixed version of the game now!
