You can beat it very quickly, not really because it's too easy, but the levels are so short and sweet, you might not even realize how much fun you're having. The harder challenges are, well, challenging, but not in an infuriating way. Nintendo really managed to make this game as approachable as possible so anyone can enjoy it, unless you're too picky. Regarding that, yes, the levels being too short can be a little underwhelming, but I think Mario works better this way. The variety in presentation and gameplay elements the Wonder Flowers provide make up for the simplicity in mechanical depth, but it's still Mario at the end of the day, so you gotta expect a game that's very basic in nature, even though it's a high quality product.
