The only ending I have no idea how to do is secret 1, so I'm still figuring this out, anyways This is amazing game!
EDIT: I got the last ending nevermind :)
So, you have to touch the stairwas just as you are close to getting hit with the moving pictures, and you will teleport to the outline in the center
I found this ending, yes, you have to do literally nothing in certain part
