"Cigarette" and "Killer" are only a couple of the words I can actually pick out in this Japanese (?) game I dug up somewhere.  You play an enforcer set out to extinguish all the smoking cigarettes you can find... with your water pistol!  I freakin' love it.  Seriously, whether you're a smoker or not, I think you've got to love the style and attitude of this game.  Good stuff, it is.  Enjoy!

(This game is not high-score enabled, so just jump in there and have a go at it!)
