YOU HAVE TO DOUBLE CLICK THE FLAG OR THE GAME WONT WORK!! It points to your mouse. Space or click to shoot. move forward and backward with up and down and w and s. Shoot the red ones. Kills says -1 when you start but goes to 0 when you hit play. The AI isn't overly hard. The AI's shots will always hit you unless you move out of the way.
Thanks to wuppyguy for a little of the coding. Have fun! I made all of this with scratch elements.
