Building virtual novel decision branches can be tricky. You need to ensure that each branch makes sense within the context of the story and that there's a balance of consequences and rewards. Start by mapping out the main storyline and then branch out from there, imagining different ways the story could unfold based on the choices made.
Well, to build good virtual novel decision branches, first, you have to have a solid plot framework. Then, come up with diverse but logical options for each decision point. Also, consider how these decisions affect the overall story arc and character development.
You need to start by clearly defining the possible paths and outcomes. Think about what choices your characters or readers could make and what those would lead to.
