Prior to its release, I was on the fence about Yoshi and the Mysterious Book. It was certainly lovely to look at, and seemed like a potentially really fun and creative game, but I was worried about it being condescendingly kiddy and easy. I also had a certain other concern that I will address towards the end of this writeup. However, I ultimately decided to take a chance on the game, and I’m very glad that I did.
Fair warning tho, Yoshi and the Mysterious Book is not for everyone; rather than being a traditional 2D platformer, it’s something of puzzle adventure game without much real platforming action to speak of at all. The way Yoshi controls and feels is very familiar, and the entirety of his classic moveset is still intact, but the levels now firmly revolve around exploration and experimentation, rather than traversal and overcoming obstacles. Hell, Yoshi himself is now completely immortal, and unlike for example Wario in Wario Land 2 and 3, there’s no meaningful penalty for getting hit by enemies either.
Each level is dedicated to a creature (usually, but not always, a Yoshi series staple) that you’re supposed to interact with in different ways to learn more about it, with one overarching level objective that unlocks progression. At its core, that’s it, that’s the game right there. I can see how this would be a hard sell at first, as it certainly sounds like it could be an unfocused and boring experience, but what it ultimately boils down to is Yoshi playing to his strengths; in a platformer like Yoshi's Woolly World, I totally felt compelled to stop progressing through the levels and sniff around for secrets every 5 second or so, because there were just SO DAMN MANY secrets and hidden goodies that I felt that I was massively missing out if I *didn’t* play this way. It made for an overly slow-paced and disjointed platforming experience for me, causing me to drop the game relatively quickly - and yes, I’ll certainly acknowledge that this was probably a Me thing, rather than an objective flaw with Woolly World. But with Yoshi and the Mysterious Book, the whole game is literally designed around precisely this kind of more meticulous, exploration-oriented gameplay, and so to me it inherently feels like a better fit for Yoshi.
Of course, the REAL reason Yoshi and the Mysterious Book works as well as it does is its execution: each creature that you interact with is the source of a shocking amount of unique ideas and even original game mechanics, resulting in a whole bunch of extremely creative and clever puzzles. It’s actually kinda stunning just how much variety and inventiveness this game brings to the table; back when Mario Bros. Wonder launched there was much talk about how developer brainstorming sessions had generated something like 2000 different ideas, but in terms of ideas that made it into the actual game, I feel confident in saying that the Mysterious Book leaves even Mario’s latest 2D outing in the dust. Of course, Wonder DID also have to design its levels around 2D platforming challenges, so it’s not a completely fair comparison, though hopefully it gives you an idea of what a never-ending wellspring of cool ideas this Yoshi game feels like.
Yoshi himself is also put to very good use here: the dinosaur’s familiar moveset keeps getting repurposed in so many different ways by the various creatures he encounters, whether they need to ride him, get stomped by him, be thrown by him, go into his mouth, be eaten by him or get molested by his tongue. Most creatures are at least somewhat friendly and cooperative, but some are consistently hostile, requiring you to either destroy, evade or manipulate them in order to achieve various level objectives.
