In theory the idea of only being able to talk to one person at a time and losing out on other opportunities is intriguing. However in practice each piece of dialogue is really only coherent with the previous. On top of that giving the option to review the case means that the gimmick is completely by-passable. Perhaps if you could ask a question once to any person the dialogue would have a more coherent flow? I liked the story as a whole but besides the killer it was somewhat to decipher the right answers. Overall pretty good.
