I've been following your Kickstarter for this project, but I'm not actually a backer (so I can't comment on the Kickstarter page). It seems you are in need of developers, and I might be able to help you, as I am a game developer that's willing to work on queer NSFW games and currently looking for work.
Caveats:
* My French isn't very good, so I'd need to communicate mainly in English.
* Of course I don't want to violate anyone's privacy, but I would like some clarification about why all the other devs suddenly left the project.
* I'm also a bit unclear on the actual state of the project: What programming language/game engine were you using? What is the current state of the code? What more needs to be done to finish the game?
