Mario, Peach and enemies new and old.
How to progress through the game:
Players run, jump and battle enemies as they explore all the planets in the galaxy. Since this game makes full use of all the features of the Wii Remote, players have to do all kinds of things to succeed: pressing buttons, swinging the Wii Remote and the Nunchuk, and even pointing at and dragging things with the pointer.
Since he's in space, Mario can perform mind-bending jumps unlike anything he's done before. He'll also have a wealth of new moves that are all based around tilting, pointing and shaking the Wii Remote.
