Agh not sure if all of these will influence the ending since I just... Picked the opposite things compared to when I got the good end ^^'
Off the top of my head tho [SPOILERS]
- just "hello"/"hi again" instead of the more happy greetings
- be skeptical when the others complete their hacks ("all over a parking ticket?", "all this just for a childhood bet?", "think they'll cave?")
- don't be excited to participate! Generally be dismissive and avoid picking things like "I'd love to help/call/chat"
- No talking positively about the others in the server (so try insulting their nicknames or telling them they're being mean/annoying, say things like "They aren't exactly helping", avoid compliments and stuff like "I would've like to hang out more")
- Towards odxny specifically, try to not be curious about what they say, and do not flirt lol. Options I remember picking during their calls: "What did you plan on buying?", "Just go outside and talk to people", "I thought you weren't a person", "That sounds very peaceful"
- During the final day too, avoid options that show that you care if the server gets deleted (try instead "Say your prayers hacker scum!") and again, don't be excited to participate (avoid all the YAY and LET'S GO etc), mock the choice of T9
I hope you manage to get it eventually o7
