It won't let me play!
Just kidding, I was reading some reviews and I guess people can't take the time to read the instructions, they must be French or something. Pretty funny. This was ok. I am a life long fan of MK right from the beginning. Fatalities are cool and all, but I was under the impression that you could create fatalitites from scratch, but that would be quite a hard game to program and play. I liked the graphics and the concept is pretty cool, but I did lose my interest within 10 minutes, but that's better than 80% of these Newgrounds games, so good job.
My main suggestion would be to have more charactors available, like Scorpian, Goro, and other pimp players. Maybe in the sequel (?), either way you should make more.
