Thanks for trying out this visual novel!
You might have missed the most recent post, but I've had to stop developing this project. Short version is that I've been solo-dev-ing this, with assets made by others, often commissioned. It's just too much work for too little payoff right now, so I've taken everything I've learned from this project and am working on my own original visual novel (which I'll also post here when I have a public demo).
That being said, if this was your first time experiencing this story, you could basically just pick up where you left off and jump into reading Chapter 5 onward.

The story has been done for years now, I was just trying to convert it to this format and it proved to be too much work for something on my own which isn't my own series.
