Edit: Posting this again here (originally posted on the Samurai of Hyuga Book 2 thread, not sure if this exact info is mentioned here.)
If you are on a mac using steam, you can navigate to the game (show in finder), right click, “Show Package Contents” then contents>resources>deploy>scenes then you can open any of the chapters in a basic text editor. Open the TXT files to view, and the JSON files to edit the game. If you find something in the game you want to edit while playing you find the same lines in the json file edit them, then close and open the game for the changes. You have to do it before the code fires, so before you make the choice that would use that code you are editing.
On a PC I think you have to extract the game first from the exe, then its pretty much the same thing, but if you want to make changes you have to run the extracted copy through a browser like firefox, not the original game through steam, since you cannot alter the original on a pc without a lot of fuss.
EDIT: That is for Steam, if on google chrome on a mac you just navigate to the app’s folder in library (might be hidden folder) >application support>google>chrome>default>extensions> then find the folder that has the game, then it is the same as above just find the scenes folder. I’m not sure for google chrome on a pc.
If you want to edit things
If you want to edit things, not just look at the outcome of choices, you have to be careful. You can easily break the game if you don’t know what you are doing, for example the game might rely on a check of a skill between 10 and 20 (something like “if skill > 10 and < 20”), since at that point in the game the max skill you could get would be under 20, and you put your starting skill in startup to 50 you are going to break things, unless you change the skill check to equal or greater than 10. Usually if a game is coded well then they don’t put upper limits on things so its harder to break, but keep in mind what you are editing, and how you are editing things. And don’t add extra code lines, so if a choice doesn’t have any reward/stat change and you add one, you will break things. You can however just change rewards/stat changes that already exist. It is easier to do all your stat changes in the startup file and opening prologue/chapter 1 since they usually set things up quickly. I usually change the default names list so my name that I want to use is the first choice, and I don’t have to re enter my name each time I restart.
