Just a few rather non-important and imperfect thoughts about this cool game.
She is using a post hoc fallacy, a logical fallacy of retrospective determinism.
Arguing that a world is some strange matrix or computers feel are all being cut by an Ockham's Razor, and belief in such ideas are like belief in Russell's teapot. Reminds me of "plants have feelings to", from my life as a vegan.
Fantasy is sometimes a way to question the validity of relevant moral choices by disrupting the normativity of real boundary situations that are of existential value (in Jaspersian terms).
And of course, free will is not a metaphysical hypostasis but relative description born of dependent origination from context and opposite polarity which is determinism. These ideas have no self-abiding nature, but are mind creations - descriptions used to better comprehend the totality of life.
I don't know, but it appears to me that questioning free will requires other mind to do it, and this other mind is either 1)free to do it or 2)also enslaved but requires another mind to enslave it or note that enslavement, and then the matter goes on ad infinitum and tells us nothing. If we reject this line of reasoning, there is no mind, and therefore no problem (the absence of possible freedom to be saved).
Wovon man nicht sprechen kann, darüber muß man schweigen.
Also, I was frightened by that blackened moon, I imagined the evil symbol of Black Sun and I had thought that the girl is a Nazi at the beginning. Anyway, I felt bad that we cannot rescue them or something.
Such a thoughtful work, cheers!
