NOTE: The Patreon version apparently contains 10 different characters (such as Ermac and Rain) plus some more stages. No idea, but this was certainly worth sharing, as there is potential for others to fix it and give it a more solid feel, plus obviously, the characters themselves could be quite useful for anyone who wants to build their own MK characters, but with using a simple START button function to switch between different characters or fighting styles. Overall, its pretty decent, but as said, its the beta build, as everything else is PRIVATE and apparently being sold on his Patreon or something. However, what makes this game interesting, is that every character has different 'stances' and 'combat styles' by using the START button (usually its ENTER) which will allow for you to switch between different fighting styles, similar to the Mortal Kombat GBA game.
here is all that remains of that 'sold' property, mind you, this is the beta build, so I'm pretty sure things aren't as refined as they could be. A game created by Gary Fisher (also now known as Shinnox), decided to try and sell a Mortal Kombat MUGEN game as though it was an original property.
