It's a pretty fun game. I like the guns and the rolling animation for the characters. I will say, I would like to have a normal jump and the roll jump as two separate things and/or speed the roll jump animation up by 2 or 3 times. It would be cool to see the players bullets move a lot faster across the screen, and maybe make the enemies bullets easier to see so you can dodge them better. Those were really all the things I could find that would make it better. I think it's really fun, so good job!
