In all seriousness now, this game has amazing animations (which is a rare feat on its own) and amazing character models, the rendering is marvelous and the map itself depicts a very cute city. The biggest strength this game has and what tells it apart from the others really are the very well done animations that are both well produced and plentiful, and give the characters a lot of personality and "humanization" - like Sara's expression of shock when she sees a dick for the first time.
The game feels very alive, and has a huge potential for as long as the due investment of time, money and energy continues. I really think this one can be big. Keep it up, boys!
