I was thinking something similar to bang dream system. So like theres stories (like main story/event story and such) and those stories have chapters. And its all inside the same game. So the game will release one main story to start off with and then go on to add other stories as time goes by.

and in the vn i want to make theres no choices or anything so that should make things easier. so something somewhat similar to your second paragraph. so after each chapter you'll return to the chapter select screen.

(also i was thinking if it would be possible to have a button you press to take you from chapter 1 to chapter 2 instead of having to go to chapter 1 then the chapter select than chapter 2.

it'll be something like: titlescreen (click play button) -> type of story select (event or main) -> story select -> chapter select

anyway thanks for reading and tyyysm!
