Super Mario World has a huge amount of levels across many different worlds. Some levels have more than one exit; there are 96 exits in all. However, each exit is a blast to find and finish, as this game has some of the best controls of any 2D platformer.
There are also many power-ups, as with most 2D platformers. There are the classic Mushrooms and Fire Flowers, but there are also others that are new to the game, like the Cape, which lets Mario fly through the air. Yoshi also has some power-ups.
