2 ways:
The original plan was to go further. Book 1 was planned to have 3 Chapters. But after releasing Chapter 2 I realized that it's either going to be a huge Chapter 3 which will take a long time to develop, or I need to split it.
Went with the 2nd option since the first would've meant a release toward the end of the year. There'll be a lot more "Neverwhere" in Chapter 4.
Hard to tell, I don't know the wt, but 2 spots where you can actually lose points come to mind.
If that doesn't help, feel free to contact me and I'll get you a list with all Kaija points.
