The last sentence is only partly true.
As KstGames (the author) admitted himself, he needed times before he fully understand the 3D part of Unity. Therefore a part of the game, especially all the early actions, is purely statics. They are rendered in real time, but without possibility to use the camera.
No name come to my mind right now, but there's few other Unity games that follow the same logic ; real time render, but no possibility to use the camera.
Plus, I guess that "real time game" shouldn't apply here. It's real time rendering, but for it to be a real time game I would expect a bit more freedom, not just the possibility to move the camera around.
