As I understand it, you have access to ALL of the content of the game regardless of your RS and SL. So there is REALLY no need for a walk through for the game. If, like me, you want high scores, then just note your scores before a decision needs to be made, and select the text you think is best. Then note the scores after the decision. If they don't seem optimal, just roll back and select another text and note the scores after that decision. I think that there may be one case where you may need to roll back more than twice to determine the best choice (the evening that Lily comes to stay at the house comes to mind where you have to interact with both Cascade and Lily). You then can roll back once more (if you don't have the best result at that time) and select the best choice.
Bonus: You have now started your own personal walk through if you write down the best choice and the situation. Then, you never have to roll back at that decision. If you bite the bullet once, you have a complete walk through up to the current update. Now you only have to do this for new content and add to your current walk through.
If anyone has any questions about a particular choice, send me a message and I will try to help.
