There are some fun levels, but a short amount of difficult special levels. In previous 2D Mario games, we got an abundance of special worlds to make up for only getting 6 main worlds. I guess there are 7 main worlds, but it still felt short. Some how, they royally screwed up the camera system in the game without offering a way to correct it. The camera follows the person with the crown. In some levels, the crown will change to the person doing better, in other levels it is fully dependent on who did better in the previous level. The fact there isn't an option to just make player 1 always have the camera is a big downside. This is a really mediocre 2D Mario. I'm trying to think if there is another 2D Mario it is better than.
