This game's really simple and pretty silly. A cowboy is assailed on all sides by tumbleweeds. Endless, rolling tumbleweeds. The cowboy must use their comically oversized bullets to destroy the tumbleweeds before they are overwhelmed.
Arrows move, Z fires.
In a shocking display of modesty, this game was inspired by my own tweet: https://twitter.com/PROGRAM_IX/status/706624643826847744
