what do you mean there isn't a guide? there are precise details on what is needed for almost every scene in the phone
#1,506 the only detail that is missing that I'm aware of is that nothing tells you about Rachael's 10 day delay before she starts drinking.
So what is confusing? or are you looking for a walkthrough? most of the stuff in this game felt very intuitive IMO (the stuff that wasn't tended to be the unimportant stuff)... try giving details about what exactly you trying to do and how the ingame guide fails to accomplish this, then even if nobody can help you the Dev might be able to use the feedback constructively.
