Synopsis

Succubus Advent: The Ethereal Collapse by AdrihelDev is a story that begins with you living a mundane life with your uncle and lifelong friend on an island with few inhabitants, secluded from the mainland of Avalon. Little do you know, an ancient evil is planning its 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. The game has NSFW CGs leading to the main character’s death and subsequent game over.

Changelog

Update 0.13a - Fixes & small changes Selena related changes & fixes:

  • The second CG event should now trigger correctly.
  • Small quick edits & additions to Selena's second basement event & CG
  • Selena not being present on the last day (during the day) of the update is now a feature instead of a bug and fixed accordingly. (Making it easier to find her second CG)

Other fixes:

  • Fixed two of the old CGs not getting archived for the build which caused a black screen on them
  • Some audio filters not being properly reset at the end of some CGs
  • You will now get your level increased to 5 and skills tree unlocked with two appropriate weapons added to your inventory if using Chapter Select for Chapter 2.

(All changes should retroactively apply to any saves with any of the issues)

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.
