I have some scenes missing in the gallery. How can I find out how to unlock them?
Even I don't really know the answer to this question! While the game has somewhat of a path structure, each scene can have any number of variables and triggers associated with it. A wiki would be a good place for this kind of thing, but I don't think anyone has made one to my knowledge. I wish I had time for it, but Chapter 5 is taking all of my time right now 😁
