“Succubus Advent: The Ethereal Collapse” is a game based in a world hit by a cataclysmic event and besieged by Succubi. Features include RPG elements, animated NSFW CGs and animated environments, a heavy focus on Femdom and Energy Drain.
You live a mundane life with your uncle and life long friend, on an island with few inhabitants, secluded from the mainland of Avalon. Little do you know, an ancient evil is planning it’s return. You’ll discover new hardships, reveal mysteries, fight Succubi and other creatures, interact with your (not always) helpful companions, and seek an end to this great threat.

- A CG transition near the very start needs to be smoothed out
(All changes should retroactively apply to any saves with any of the issues)
