Succubus Advent: The Ethereal Collapse by AdrihelDev runs a female dominationRPG focused on Succubi and the energy-drain encounters they specialize in. You start a mundane life with your uncle and lifelong friend on a secluded island off Avalon's mainland - until an ancient evil starts maneuvering its return. The game is a story-driven Ren'Py title with turn based combat and a quest structure that mixes mystery investigation with combat encounters. Femdom Succubi are the primary antagonists, and Energy Drain events can lead to game-over states with NSFW CGs leading into the protagonist's death. Expect 2dcg, animated scenes, fantasy worldbuilding, monster girl routes, point & click navigation, rape and vaginal sex content threaded through a story where losing isn't just losing - it's how the more interesting scenes unlock.

Developer Notes
AI art is used in the game, I understand it's not to everyone's liking. I'd love to use actual artists but due to it just being a hobby and especially my limited budget constraints (My lacking art skills also doesn't help) it's used for now. This is a project I'm continually working on in my spare time (Mostly Weekends) for fun, as such the game is and always will be FREE for ALL updates. It will be updated as I finished each part (Short Prologue first then parts of each chapter), I can only hope you get some entertainment out of it as I get creating it. Feedback is greatly appreciated and welcome, as I'm always happy to take it into consideration and keep improving future and existing content.
