== Gameplay ==
This game is that of a platformer, but very different from Super Mario Bros. You have these new abilities that will be very useful to get to the end: Eating enemies and making them into eggs, the Flutter Jump, transforming, and many more. You also have Baby Mario to deal with. Each time you're hit by an enemy, Mario will start floating around in a bubble and crying. Until you get him back, you'll lose one Star Point per second. When your SP reaches 0, some flying enemies will take the Baby away and you'll lose a life. If you can get him back, however, you'll regain SP gradually if it went under 10 until it reaches 10 again.
Your main attack will be eating enemies and turning them into eggs, which you can throw at enemies to kill them. There are a few different types of eggs that you can get, all of which are different.
