Nice game, I like your implementation of the theme..It is hard after a little bit to remember which one was the blu one.
I notice could of think that you can improve.. Shooting is going from the player and not from the gun. Also when you kill all the "reds" the blu continues to shoot to you.
Really good job for your first release..
