The prologue choices aren't that necessary (ex. for a couple of them), you just need them to get the desired route. They don't give you "relationship points" or something important for the main story and don't affect the outcome. Though they give you points to start a correct route, the amount doesn't really matter. For example, if you want to read the Crowven Route but also want to hang out with other characters a bit, you just need to make sure Crow's "start points" are higher than Twy's and Reggie's.

I checked all the info via source code, but if there is a mistake somewhere, don't be shy to correct me. Plus, I'm not native, so take it easy on me, would you? Nah, it's not an excuse. You need at least 11 points for each good ending (to get the bad endings, plainly do everything vice versa, after you start the desired route). The choices for the True Ending are underlined (9 "true points" for Twy's and Crow's routes and 10 points for Reggie's route).

I'd strictly recommend you to try to finish the game by yourself at least once, but well, if you're already here and reading that, I guess it's not an option for you, so let's get started already.

best boi don't change my mind he didn't deserve any of this

6. "Not today, I'm not hungry!"

8. Call Mystery Number--Was that you?
   
9. Call Crowven--He's family, he'll know what to do!

    • Block-kick-jump-kick-punch;
      
    • Charge-punch-kick-kick-block.

i'd marry that gorgeous lady immediately don't judge me

1. "Will you tell me who you are?"
   
2. The library (or hang out with Crow if you want, and answer: "I want to be her friend...").
   
3. "I'll try to distance myself from him."
   
4. "Who you really are."
   
5. "I'm meeting with a friend for breakfast!"
   
6. My 13th birthday.
   
7. Call Mystery Number--Was that you?
   
8. Call Twyla--Could it have been the killer?
   
9. "I guess you have a point..." (+1)
   
10. Don't keep Twy waiting for too long, i.e. don't let the sailor book seller show his scrapbook to Mary. (+1) However, you can sacrifice that choice (if you do everything according to the guide, you'll still have plenty of them) to become a bit closer to the True Ending: "I just wanted to say hi" / "Do you sell anything other than books here?" -> "That won't be necessary" -> "I've got time!" But again, if you do everything according to my guide, you'll still have enough of "true points" too, so it's entirely up to you.
    
11. "I suppose." (+1)
    
12. Stay silent.
    
13. Lie x 3. (+3) If you are honest with her, you'll get nothing but a bit different dialogue about "it certainly helps me a lot." It has no impact on the story. If you're interested, I'd recommend you to save here, check out the "honest dialogue" and then reload.
    
14. "Telling me who you are."
    
15. "I'll be at the cemetery by then, surely." (+1)
    
16. Handle the situation without her. (+1)
    
17. "We don't know each other."
    
18. "How did she die?" (+1)
    
19. "There was an emergency today."
    
20. "Analysis?" (+1)
    
21. It has to be here. (+1)
    
22. "Do you believe in ghosts?"
    
23. "You bring up a good point..." (+1)
    
24. Girl. (+1)
    
25. "I want to believe Twyla is a good person." (+1)
    
26. Go with Twyla. (+1)
    
27. "Building a birdhouse." (+1)
    
28. "Well, no, but..." (+1)
    
29. "Good night."
    
30. Pretend to do it. (+1)
    
31. "And will I see you?"
    
32. Call Mystery Number.
    
33. "Life cut short." (+1)

Enjoy your ending!

1. "Will you tell me who you are?"
