Guy started making a Tower defense game then as a joke added in a Easter egg of hamsters.
Player's really liked it. Started creating kill Chambers to get kill as many hamster's as possible. A excessive amount... Game slowly Warps into a satisfactory game about torturing and genociding hamsters.
Some game devs are all right.
And yes your eyes don't deceive you. The dev added the ability for you to fuck a hamster to death on a bed...
