A detective style game akin to point-and-click adventures of the 90s where you have minimal information and have to walk around and try things to solve puzzles. The difference is in this game, where the player is supposed to be an ace detective, it will punish you for not getting right the first time.
Having enjoyed Devil's Daughter, I was looking forward to a more open-world version. Unfortunately, more world just means more time spent moving between places.
