I've been thinking about the "multiple protagonist" tag, a topic that came up some days ago. After completing the latest update (it was sooooo short
) I don't think it has anything to do with the sister being introduced in the story.
This project is nothing but a kinetic novel (it is tagged as such) and so far none of the few choices seems to have any impact whatsoever. In fact, if I apply Unren to the game and open the dev console there isn't a single variable in the code, at least apparently.
We've always been nothing but spectators of John and Emma's misadventures from a 3rd person point of view, and now that Amelia has arrived it will essentially remain the same but with one more protagonist. We're not John, but mere observers.
