Attempt to hit your opponent with your green laser beams! If you hit a green barrier, you lose. If you get hit, you lose. The purple barriers block only the lasers, you are unaffected. First to five points wins! For blue: a: left; d: right; w: forward; s: back; space: shoot For red: 4: left; 6: right; 8: forward; 5: back; down arrow: shoot
As an extra challenge and benefit, you can move your shot lasers by turning. One small problem though, you turn yourself at this time too. Also, if you're holding down on a key and your opponent presses one of theirs, your action will stop. So rapid-fire tapping of keys is the way to go.
