I created what I call a clickthrough. I recorded every step in a Libre Office Calc -- install the correct filter if you want to use it in Excel -- spreadsheet and played to what I think is the end of the v0.15.1 edition. This took 76 "game" and 1765 actions.
I hope to use this to see were stories are connected and so optimize the play. The walkthroughs I found are all based on one of the stories, but for me it is not always clear to which point another story must be finished to go further with the other. In the end I hope to have the most efficient path through the game and finishing all the stories
In this play I was overwhelmed by all the new stuff in school -- great addition, it makes the whole game mch mire enjoyable! -- and forget the Mia story. So the 76 days could probably much faster. And before I forget, no cheats for the skills or money are allowed if you want to do it better

Skipping the minigames -- even for the money -- is fine.
