My game: RED vs. BLUE

This is my game, RED vs. BLUE, which I made in scratch. I got the idea for the game after creating my first "game" (RED DEFENSE), and then spending a little while trying to make a Pong rip-off. Combining what I had learned from making these two "games" I was able to create this game.
Instructions:
Red: W=up S=down D=shield A=laser      
Blue: Up Arrow=up Down Arrow=down Left Arrow=laser Right Arrow=shield
