Some quick Tips for the 7.1 version:
As soon as you enter the game:
#1 Once you go through the initial dialogues with Anabel and her friends - go right to Soul sorting and unlock all levels
(You will need to spend a few days to do this)
#2 - talk with the Angel to obtain Your Read mind and Watch dreams abilities / talk with the Devil lady (you will wind up in her office while exiting the Angel's office through the elevator randomly once you have the first 2 abilities) To obtain the Arouse ability
- this way you have all available options while interacting with characters early on in the game. This includes some one time interactions like the Bus/Subway interaction.
#3 After getting invited to the Party - steal clothes from store / Dont drink at party leads to the lengthier story arc, with more scenes. (involving Job search for Anabel ending up at a strip club, and hopefully more in the future).
#4 When interacting with characters always go through Read mind / Arouse options to see if it has an additional effect - sometimes it leads to more interesting things happening later on.
#5 Jogger lady (park) - after using your abilities on her and convincing her to come back to the park late at night - check the bush during night time.
#6 Before Anabel starts going on dates with the "Jake" character - make sure to visit the park and Cinema alone and observe what other couples do there - you know... to have some ideas for the future.
Visiting these places when Anabel is not there is also interesting sometimes.
You can do this by whispering to Anabel in her bedroom after school while she is studying.
Finally i have a theory...
The Homeless person that you see everywhere... in the park, in the bar, in the cinema and even in the strip club. You cannot influence him with any of your abilities, abilities that are effective when used on everyone else. You cannot read his thoughts, you cannot make him panic by yelling "fire!", he is impervious to your arouse ability...
I think he is GOD in disguise... snooping around, observing, waiting for something...
Almost where ever you go, HE is an ominous presence at that location.
A mystery...
