Mario can get a bee suit to fly short distances.
Gravity plays a big part in this game and it looks good.
There's a Boo-suit. Mario becomes a Boo with a Mario-hat, but they don't show what he can do.
I see a Yoshi-egg!
The pointer definately has a big role here, but I'm not sure if in this movie it's controlled by the same person. Mario runs around way too freely to worry about firing at enemies with the Wiimote pointer.
It looks like you can shoot items at enemies to stun them.... maybe that's a second player who's helping out. It would be nice to have your girlfriend help you out by firing away.
