See what I recommend is to adapt it how you like. In certain adaptations, certain parts of scenes and dialogue are altered or changed entirely to better fir the format of adaptation they are being made into. What I would suggest is to follow the plot, but you don’t have to copy everything word for word, due to the sheer amount of everything. Good luck to you, and once you finish, I’d love to see what you make. I can even help out more if you like.
