Is there a page where you can see a changelog of previous builds so you can see if there might be a piece of content you might be missing as you go along a story arc?
Are you referring to a guide of of the chapters and choices or what has been updated through each build? If it’s the prior then no, I have not personally made a guide. If it’s the later, the current public build 1.00 goes up to Chapter 7 for each character route and 1.01 goes up to Chapter 8 Koshiro
