It's been a while, but...
Isla Femme is making progress!
I've settled on Twine 2 Sugarcube, a HTML based designer that lets me build a game with minimal coding and mostly writing, which is what I needed. Additionally, it'll let all of you play the game without downloading, if you don't wish! If you're familiar with Free Cities, Isla Femme's UI will look very similar.
Once I have a list of scenes and included fetishes, you'll see more posts here, but I'm writing a main narrative now. Our Beta build will likely be small with just a few scenes, but it will be the start of a much larger game.
