Hi Neco, to answer your question, they are actually all connected to the game in a strange way. The end of the game requires you to interact in such a way that a lot of people really enjoyed (as it can get a little personal), and as a result a few of them left some comments. As much as the old adage goes that "any press is bad press", I wouldn't bother keeping bot reviews for a game of this size as I'm not really making any money off it, so the niceties of people's reactions to it are enough for me.
By the way, I just played it and beat it - Was pretty damn interesting, I do have to say. It was as I expected, within a few twists and informative and meaningful messages given. I just wanted to be sure of one thing though, if it's alright that I upload a complete walkthrough of my experience with the game. Editing will be a nightmare but I have everything in order for a 3-part series of this game. I'd prefer to ask for permission on a game like this first though.
