Hi Bobby,
I downloaded the game and it runs very smoothly, though I could not play with anyone .

My only suggestion is to do with the control system. I don't think the mouse location should determine which way the play moves. As the game is 2D, All player movement should be handled with the WASD keys and aiming and firing should be done with the mouse. They should work independently. This would then allow you run in one direction, while shooting in the opposite direction.

Anyway, just a thought.
