Idk it was mostly just funny because of the narrator imo. You do have a bunch of valid questions, but I guess this is more of a piece of art that leaves this up to interpretation. I remember the avhievement you get for not playing the game for 5 years, so I feel like the game was maybe trying to say something about our increasingly digital life and how that narrates our reality or something. There are mamy different endings though, so I'm sure there are plenty of interpretations

Also I think the game was an exercise in what you can do when you choose a video game as the medium for your art. Its the first time where it was possible to let the main character defy the narrator. That would't really work in a book.
