I like this idea! Can you describe how would you like to skip through the story? I’ll try to make that happen. :D
- In the meantime, we currently have a skip button that fast-forwards every seen dialogue and stops only when the player needs to make a choice to proceed. We also have a save/load system with automatic saves (seen on the preferences screen). I know it's not like the feature you want (now I want it too), but it could make things easier to avoid already seen content.
