Super Mario Maker 2 brings some incredible, fun, and entirely new elements to the Super Mario Maker formula. Almost every single addition, big or small, feels fantastic and works phenomenally well, with one exception: I cannot figure out who co-op level building is for.
If you've played any of the New Super Mario games, you know co-op play can be an incredible experience. It can also tear friendships apart. In other words, it's wonderful. Co-op level gameplay is part of Super Mario Maker 2, so you can make your own levels and then scream at your friends and family to "pop my bubble!" after you miss a jump or take a direct hit from a fireball.
