The game includes a few buggs, the first one is a certain spot between the fence and the most steep side of the slope behind the church where you get completely stuck, the camera twiches and you cant see a shit. The second bug is that your camera can hack trough the church walls which is annoying, and the third and last bug comes from the latest patch (0.2), in this patch you need to press ESC to reach the options tab, in doing so you exit fullscreen mode which is probably not intended.
