It's fine. What bugs me is the people who say 'Wow, such an amazing game, if you don't think it's incredible you obviously don't understand the message, and are therefore an idiot.' You'd be better just watching E.T, it conveys a similar message whilst actually being good.
Not exactly deserving of the title 'masterpiece', which people on this site tend to throw out whenever a game has a semblance of deeper meaning and doesn't involve vast amounts of killing, but kudos for making at least a vaguely original game.
