It was good for a demo.
This is a great game, but it definetely needs a whole lotta work. First, don't make Zero jump so damn high. Second, make a button on the first screen so you can skip all the instructions crap if you've already read them. And, when you get killed my a bad dude, don't make the game just freeze up. Make it go to a screen that says something like "U lose, try again." But great job, and I know this is still in the works.
