Nice site in general. There was a bit of clipping on the image for the “coming soon” game and I was a bit confused by the categories (I had scrolled down so I could see the categories, but not the stories under it, so when I clicked on a category nothing seemed to happen. Maybe trigger a scroll when you click on categories?).
With respect to the stories, I only played through a couple. Are they built on your own game engine, or an established one? If the former, I would suggest considering adopting an existing narrative engine - it will make it much easier for yourself in future (also - always better not to reinvent the wheel). I’m a fan of Ink myself, but any story scripting engine with good tool support is helpful. Also, it would make it easier for others to contribute if you can offer them a toolset they may already be familiar with.
From a gameplay perspective, I felt the limitation to 2 choices only quite constricting (at least in the couple I tried). Unless the choice open to the player really is binary yes/no, I’d recommend expanding the stories to provide a greater sense of agency. I’d also try to limit the amount of text per section into what will fit into a text box, but that’s more a personal preference.
Good luck with this.
