Nice little game! Quite hard, and I didn't expect the friendly fire, but that's how you game stands out with an idea that is popular among the jam ^^.
It was really hard for my brain that the blue character was the one that shoot red stuff... Yeah, I know the guns are in a different color, but it's mostly the character's color that stands out, so I would have done the opposite.
But it's still a good game, congratulations =)!
