That would be interesting... I will talk with Loling (the main dev of this game). I would like to add it. Thanks for the suggestions :P (A walkthrough? What was your experience with it? How could it be done?. Just thinking)
Well walkthrough is something of a play guide for the VN. If we somehow go to a wrong path or like when we choose a option and because of it the future options will get affected. For example if I choose angry and tough at first, the mc's charm will be low because of it during the car ride to the institution there won't be that many options left to choose (only two ig)..... If this doesn't help, you can see Eternum's walkthrough.
