I have been struggling with the pull-lever-throw stone-run for a timed door puzzle on level 5 and there seem to be no way to resolve it. It has been so bad I think I would return the game if I could. I read forum posts and watched walkthrough videos, but it does not help. I am hitting the grate whenever trying to reach the open door, and when I try to get through the door it pushes me off even when it looks still open, and then closes. It has been truly ridiculous and unreasonably time consuming to try to get through. People in the forums mentioned turning the timer off in the options but I cannot find such option. Maybe the puzzle is designed with some specific joystick or keyboard in mind, I don't know. I am playing on a desktop. If I try to keep the movement keys pressed, it constantly overshoots and gets me too far. Anyway, I keep hitting the grate, it stops me, and when I finally get through, the door slams at my face.
It would be a total shame to have to abandon the game at that. Why is this puzzle so ridiculously bad?
