The Hills Have Butts
From Aidan Wiki
The Hills have butts is a build of an assignment that happened to have a particularly amusing bug. It was developed during the fall semester of 2016 by Aidan Markham.
As soon as you enter the game, deer butts will spawn all around you. The game will eventually crash because so many butts will spawn.
The game is available for download from aidanmarkham.com. Direct Download
