This trilogy is a 60 hour journey! But it is a great journey, I was surprised how many of the background story threads got intertwined to the cases to form a narrative across the three games. I found the dialogue and the little side jokes entertaining, but the humor could be described as finely aged dad comedy.
There’s not much I can say without spoilers, apart from beware that this is a visual novel and there is not much of a gameplay otherwise. If you are expecting puzzles and minigames, this might be a disappointment.
