Short but good, evidence might sometimes escape you but it is there. A bit longer and meatier than the first game. Charming characters and lots of drama while still keeping it light-hearted and funny. They even improved on the quack button! Sometimes the notebook seems omniscient because the scenario isn't complex enough to really rule out another interpretation, but that's just part of getting the style of the game and the devs. Don't overthink this game.
Only for people who think a video game about combing through files sounds (potentially) fun, but there is also a tragic story in here and a real crime-mystery to understand. It will also not tell you what to search for, except for a straightforward suggestion in the beginning to get the ball rolling.
