7 different endings is a crazy impressive amount of work for a SOLO dev in three days. Truly amazing. I sadly got stuck on the first puzzle ;-; I figured which item is supposed to reveal the number, but I couldn't figure out how to actually reveal it. Maybe someone can help me out? Either way this gave me old Nintendo vibes and I dig it.

Yeah, that is the only number that isn't explicitly told, and the visual clues aren't really apparent. Should have made it different in couple of ways. If you still intrested here's two tips. First - the text of the book allude to the amount of something. Second - there is a visual representation for characters from the book in the room.
