About This Game

Your humanity is at stake.

The game features a corruption mechanic. The more demonic energy seeps into your veins, the stronger you become, but, your soul is at stake. Certain dialogues, romance options, cutscenes, and the ending depend on the level of corruption you have accumulated. Will you stay on the side of humans? Or ... perhaps...

Engage in sexual activities.

Experience the game in a fully immersive way, everything being presented from the perspective of the protagonist. But be careful, the stronger the demon, the more corruption she will gift. Depending on the location, demons can, and will want to use toys to further improve the experience. 

They are not alone!

As the link between the human and the demon realm has been made, they will bring upon you their spawn, in various forms, from ghosts, ghouls, skeletons and anything else you can think of. Use various weapons to defeat your enemies. Some require brute force, but some need a good whipping. But know that these creatures will keep on coming, no matter what. The only way to get rid of demon spawn is to cut off the head of the snake!
