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.
