I was getting frustrated with it, until I discovered that you have to reach HumanBot's ending first before Annie's ending opens up, and then eventually the rest of the game. I also thought that the "Wrong End" might have been a bug or something, since it was abrupt with no real lead-up, but I guess the choice that triggers it ties into the actual ending of the game.
Anyway, great work. Quite impressive for such a relatively small project.
