They said it was done on MUGEN game engine and they are only teenagers who made the game. Plus since most of the sprites are from Nintendo, unless they allow it, it would be impossible to sell off the game so we might be playing for free
So cool!
this games pretty fun at the beginning, but trust me after u get past the extreme amounts of lag, and pretty poor looking graphics. Its actually not a bad game. Highly repetitive though just to warn you guys
