The story is planned to be quite large, with many chapters. I don't have an exact number yet, as I want to give the story the time it needs rather than force it into a specific length.
There will also be multiple choices throughout the game that can have a real impact on how the story develops, although many of the bigger consequences are planned for later chapters.
The same applies to the love interests. My goal is for every LI to be optional, and some relationships may be more difficult to pursue than others depending on the choices you make.
