The controls take some getting used to so a single player mode would really help. You don't need AI (though it would be nice) you could just have targets randomly appear to give the player a way to practice moving and shooting. You could have challenge levels where you need to shoot all targets before time runs out.
From the screenshots alone, I think you need to desaturate the floor a little bit.
