Super freakin' fun, Mario Wonder takes the really polished (but also kind of stale) formula of 2D Mario games and gives it a new life. The new transformations are pretty fun, but where this game shines is in its level design. It has some of the most fun and memorable levels of the franchise and the use of wonder flowers gives them a lot of trippy personality. The multiplayer is also really fun, after playing some other Mario games where it was kind of infuriating this one gives a perfect balance of fun and challenge, I played it with my sister and we were laughing our asses off every two minutes. If I had something to critique it would be the boss battles with Bowser Jr., they're fine but they can get pretty repetitive, and they're even worse if you compare them to the rest of the game and see how little imagination was put into them. This is solved with the final boss though, as it's one of the most fun and challenging of the franchise. So yeah, as you can gather from my rather hyperbolic review, this game is tons of fun and shines with imagination, it may be the best 2D Mario game ever.
