I absolutely loved the format of this game! By the way, I think the missing pages people are mentioning went outside of the book's frame to the top. This may be a bug in this version of your game, but I think you guys should explore something like that as a game mechanic. Writings appearing in the wrong, or unconventional space could be used to convey the dwindling sanity of the writer(like in a book I started and didn't finish, called House of Leaves). Hell, all the events have been happening within the pages, but maybe you could even have something happen right outside the books on the table (ghost hand appears as the writer writes something they don't like?)
I think there's a lot of potential here, and it would be exciting to see you guys make this your niche and explored more.
