So, basically, two main stats you have in the game:

1. “Zu-points”

2. “MC-points”

While the second stat is not so important (for achieving the Good), the first one is the key to get a “good” ending

Zu-points help Zu to become more stable, to help balance out his mental turmoil, help him understand what's going on in general. If you don’t have enough of them, it may lead to some bad consequences.

This guide will help you with getting good “Zu” endings.

 ____________________________________________________

First of all, through the whole game, you’ll see choices that will actually give a minus to your Zu-points. I’ll just put them here

1) "Hug the savior!" [-1]

2) "Sybil, can you tell me more about yourself?" [-1]

3) "Lasse, can you tell me more about yourself?" [-1]

4) "They don't have a soul" [-2]

5) "I felt awkward - we should be inconspicuous, no?..." [-1]

Choosing these will minus your Zu-points, but they can be useful to help you get other endings (not only bad endings)

Pre- and festival episode game:

1) "Yeah, sure."

2) "Fine, I’ll let you pay for me..."

3) "It's from Zuzu!"

4) "Nuzzle my face into his chest."

5) "Express confusion about his reaction."

6) "Okay, that’s embarrassing. I won’t hug him."

7) "Talk to Zu to divert his attention."

Or

"Cling to Zu to distract his attention." (will give you some “Mc-points” as well, be careful)

8) "Kiss away this droplet."

Or

"Lick the droplet away." (gives you “MC-points”)

Main branches:

After calling Tiller/Marci:

I. Helping Anna’s children:

If you did everything right before, you have enough points to achieve the good ending.

Just be sure you didn’t hop on the negative Zu-point choice.

II. Buying the code:

1) "They have a soul"

2) "He’ll make sure we’ll always be together. No matter what. I trust him."

After calling Zivil:

1) "That's why you're always there to protect me, right?"

2) "I enjoyed this affection quietly."

3) "We're going to leave, right now!"

________________________________

but what if you want to achieve the MC endings?

Gives minus to MC-points:

1) "Linda is not a real person and her voice is not real either. It's not art or work. It's replacing a person with an AI." [-1]

2) "They don't have a soul" [-1]

 Gives MC-points:

Pre- and festival episode game:

1)"Ask Zu what's wrong immediately."

2) "Hug Zu instead! I was so worried!"

3) "Don't ask anything and continue the walk in silence"

4) "Cling to Zu to distract his attention."

5) "Lick the droplet away."

6) "We have long recognized androids as individuals. Linda's work should not be condemned."

After calling Tiller/Marci:

II. Buying the code:

1) "I'll be the one to protect him from anything. Nothing ever will hurt him, never again."

After calling Zivil:

1) "That's why I'll always be there to protect you"

2) "I only pulled him closer, tighter, feeling a bit possesive today."

3) "I will get rid of her."

to achieve "dream" ending, your name must be "Anna's child", and you must follow the buying the code ending

(it's just some funny ending lol)
