Seems like a cool game! Is the solution messed up for the puzzle with the four windows though? I get you have to recreate the symbols shown on the plaques next to the relevant noises coming from the windows but it doesn't seem to work?
Viewing post in maybe I can wake up by force comments
Well you are the second person with this probelm. The time the person thought that the symbol for the beast (breath noises) was a hour glass but in fact the symbol is open at the bottom.
Is that the solution?
If so I will recreate the symbols.
But in general your thoughts are correct. You have link the symbols on the plates with the right glass wall.
