May 21 marks the Switch 2 release of Yoshi and the Mysterious Book, a 2D Yoshi adventure built around experimenting with creatures rather than surviving platforming challenges.
10 biomes structure each level as a small playground where players study critters by eating, throwing, ground-pounding or combining them, with discoveries unlocking more areas and Yoshi unable to die.
Nintendo aims the game at very young players, pairing a hand-drawn storybook look with low-stakes play that rewards observation over skill and includes customizable UI tools unlocked after the first six biomes.
The review says the concept loses momentum because many interactions repeat, puzzles usually have one fixed solution, and the story pauses abruptly at credits before a stronger second half resumes.
That leaves the game as an accessible entry point for children and parents on Switch 2, while hinting at a broader sandbox-style sequel that could better realize its puzzle-platforming ideas.
