Capture the Flag

First, press the spacebar to start the game, then use the arrow keys to control the blue spaceship. Press the "F" key to fire bullets. Avoid the red spaceship and its bullets. If the blue spaceship touches the blue flag, "You Win" will appear on the screen. If the red spaceship touches the red flag, "You Lose" will appear on the screen.
