I created a thing for Gay Western Jam. It's more of a demo of an input method than a game.
I basically thought about the jerk-off motion input method and then tried to make something around that.
I thought about making the gun penis shaped but I thought that would be trite.
If there were more hours in the day this would be a more complete parody of Accolade's Law of the West
Also on Github if you're into that kind of thing.
