Multiple solutions to puzzles (spoliers!)

[spukrian]

When you exit the library (in Black Plague) you´re supposed to make a see-saw(?) to jump up to a switch that makes a ladder fall down or something. To this day I´ve never solved that puzzle that way.

Hmm, I don't remember that puzzle at all. Was this the library with the secret door?

Yes, that´s the one. The puzzle is in the cave after you exit the library. It´s like a construction site.

Here´s a youtube vid, the puzzle starts at about 6.37, the guy who made the video makes a ramp, just like I did the first time I played:

To clarify, if he had gotten too close to the pipe with the wooden boards, they would´ve gotten stuck.
