Hi Jakster!
First of all, I'm really glad you liked the characters in LFTS!
As for the latest Demo I posted; that's not a new chapter, rather that's edited and updated version of the old demo.
Everyone has access to the demo, because I want everyone to have a chance to experience LFTS, and beyond that, yes it's charged on a chapter-by-chapter basis.
I have to do this as itch has no form of subscription.
I'm sorry if this led to you feeling confused or disappointed.
