The game took me 8 hours to complete 100% (I think, I don't know if GOG counts the time when paused). It was very entertaining, not a kind of game you find often, and some things didn't go as I expected at all. A couple of bodies where difficult to find (the one in the window of a cabin, and the one in the barrel). Several identities I found by trial and error (specially within the same rank), but I don't know if I just missed clues. All in all, money well spent.
