Mario Great Adventure 3 features 15 new challenging levels for you to explore and beat. There is an additional component to Mario Great Adventure 3 that wasn't there in the 1st or 2nd one. You must also clear the level of any and all enemies. So now you must collect all coins, mushrooms, etc AND you must also kill all enemies too. The bar at the top left will tell you how close you are to completing the level.
