I'm at the part where I have to move columns (or whatever those things are) around some specific way in order to unlock the door to get the key. My problem is I don't see a sign anywhere, except by each locked door. The signs do not give me any kind of correlation as to what, where, or how the columns are supposed to be placed to unlock and open the door. I know it's really me and not necessarily the game, but I can't figure it out. I don't understand what I'm supposed to do. Anybody, please help. Thank you.
