Adult PC Game: Undead Craving v0.1.2 Win/Mac/Linux+Save by Imadori Archive

Overview:
You play as the infamous apathetic king of the Undead, one of the "bosses" in an already dead MMORPG where NPCs are now the people living a "normal life".
Everything starts when the Demon King visits you after X years of your capture for the first time, asking for a huge favor in exchange for your freedom: inherit and become one of the seven sins, Lust.

After accepting the said Sin, you also unexpectedly gain back the humanity that was lost long ago ever since you turned into an Undead.
Now is the time for your redemption. Turn yourself around, from a former passionless zombie, into the ultimate Casanova, as the effects of Lust not only affects you but everyone by your surroundings.
