Unlike the other one on this site, this one has traditional character picking, stage selecting, unlock-able content, and more. It's very basic, but it's not supposed to do everything for you, okay?
Oh yeah, and here's a list of all the unlock-able things I included:
-Emil Castagnier: 10 battles
-Halloween Town: 20 battles
So NO complaining that "This isn't real, it only has one character!" because it REALLY doesn't.
