I agree with what Wren posted. I am very interested in what's going on here, but I can't figure out what to do other than just go through random combinations of actions until one works. I spent quite a while trying to determine the order and I thought I went through all the possibilities, but clearly I missed one or I didn't find some other piece of information. I don't want this to sound entirely negative, because I really liked the narrative and the use of public domain art.
