Wonder is easily in my eyes the best side-scrolling Mario platforming game since Super Mario Word. What really stands out about this game is the level design variety in terms of backgrounds and overall platforming themes. Even though the "Worlds" have certain themes to them (such as snow, sand, lava, etc) the levels themselves play very different, offering a great amount of varierty.

In addition to the natural variety that each level has, the addition of the Wonder Flower powerup increases variety and innovation even more. The Wonder Flower changes mechanics, visuals, physics and transforms the players to unique characters in certain levels. But there's more: Wonder introduces new powerups in the form of elephant Mario, bubble flower and drill head costume. Each of these new powerups add another layer of strategy for the levels. Collectibles are scattered in the form of wonder flower purple coins.

Controls are incredibly tight and physics extremely well-tuned, making platforming in this game very fair. It must be said though that the difficulty in this game is on the "very low" side making this one of the easiest Mario platforming games.

Lastly, the overall presentation in the game is fantastic. Colors are vibrant and animations are next-level for a Mario game. Somehow Nintendo has managed to bring yet another timeless Mario side-scrolling game so this is a must-have if you own a Nintendo Switch.
