Yep, u are right, the perspective, actually the field of view, is wrongly made in this game, since beginning (common problem with early koikatsu works). It's Most annoying in POV sex scenes, where one can see all the room around, but the girl is just a small dot in the middle. Fortunately Dev seems to noticed that, and new scenes are better made.
I think he just spend too much time playing AvP as Alien and this way of world seeing sinks in :D.
