Well, that sure was something!
Obviously spoiler ahead if you haven't played the game, I first decided to pick every alien related choices. For some reason, the atmosphere felt a bit "too normal" for a game about a girl who discovered her skeleton isn't hers, so aliens seemed like a good explanation to start.
However, as much as her "aliens build my body" story was well crafted, I wasn't buying it at all. Seeing the other rational choices made me believe she was just being delusional. So I played again and chose all the rational choices.
And holy shit.
My second playtrough made me understand her behaviour in my first playtrough. I wanted to know the truth and now that I do, I wish I didn't.
...Actually, what if it wasn't the truth after all?
Great stuff!
