From the game box:
Do you have what it takes to save the Mushroom Princess?
You'll have to think fast and move even faster to complete this quest! The Mushroom Princess is being held captive by the evil Koopa tribe of turtles. It's up to you to rescue her from the evil clutches of King Koopa before time runs out. But it won't be easy. To get to the princess, you'll have to climb mountains, cross seas, avoid bottomless pits, fight off turtle soldiers and a host of black magic traps that only a Koopa King can devise! It's another non-stop adventure from the Super Mario bros.!
