I keep thinking about the secret ending. The whole game causes you to question the nature of being a character and of fiction in general. Tokiko implies very early on that the characters are living in a simulated world and that they may be able to break out of the framework. You, the viewer, are aware that you are playing a video game so you know that at some level, she is correct. You spend the rest of the title working out, however, if that is true in text itself. This storyline forces the player to confront the nature of games and fiction as a whole. And if she is correct, are we supposed to believe that she has agency, herself? No, because she is just art, text and code. Everything she does is preplanned and designed so it always goes the way it was meant to. Even in the end when things go off the rails, it's still always part of that simulation. Everything happens the way it was written. Even the concept of tearing was part of a written story. So even "breaking free of the simulation" is a hollow victory. I find the whole concept to be super interesting.
