LOVE IT....But I got some advice...
Definately needs more characters. The ones you've chosen are badass! You could put in A-Bot, he'd be a good person. And other famous things would be good, like The Assassin in that collection. Other than that, more stages would be nice, better powerups, but yeah, you've made a game that would make a console, in my opinion! I'd get it! :P Good Work with this project, and keep up the brilliant work!
