Stuck home cause you think you have Swine Flu? Then try playing Swinefighter! I got a 13 my first time playing and haven't beat it yet. Be sure to let me know what scores you get!
Update: I just got 17!! Woot!! I think you can actually get a higher score playing here because the screen is condensed. I don't know why that's an advantage, but hey, I just got a much higher score!
To play with no condensed screen, head here.
Thanks @comosa for the tip!
