I don't exactly remember, but it was the second or third mechanism gate after a big drop downwards.
I don't really remember anything else
Although, the game actually felt very well done
oh thats just to make it so you cant climb on that side as that would ruin the puzzle
Yeah, I guessed as much, though I suppose you should try to have a difference between an activated and deactivated wall. But I guess that was just due to the time constraints
