Black Hill - Chapters

Is each chapter or episode presented from a different persons point of view?

Do we take it in turns to view things from the Priest and Doctors point of view, like moves in a game of chess?

Or do we rotate through the Priest, the first friend, the Doctor and the second friend? That way you can use the chess moves technique but also use the travelling friends as witnesses - and play with different vantage points of various plot points.
