"The Secret Of Zombolia" contains an adult version as well, which changes the story slightly. Mostly it's just additional scenes, but the story is changed in this way: in the "sfw" version, the evil spirit wants the souls of young women, while in the adult version, he want them as sex slaves. The enemies throughout the game will also change in the way that getting "hit" by them will display a sprite sex animation.
