Originally released for 3DS, the 'Deluxe' Switch edition of Layton's Mystery Journey: Katrielle and the Millionaires' Conspiracy feels rather comforting, the video game equivalent of a warm blanket. For the most part, it reverts to the core formula of the Professor Layton games, albeit with a new cast, by dividing the narrative into mostly lighthearted, charming 'cases'. It lacks the confidence to fully embrace its new setting, stopping short of expanding upon some of its ideas, but it still delivers the series' unique blend of storytelling and lots of puzzles with aplomb. It'll have fans and newcomers scratching their heads and smiling at the same time, and while it's not up there with the series' best, it's still a decent detective game.
