Hey we're glad you love it!
To get the "Meet the Demon" achievement, you'll find a secret ending by messing up with everyone you meet.
For "Night Saved", you can't get a single Surigram EXCEPT for Charlie's.
As for the "Good Ending" it's very specific:
Get Elliot's Surigram
Mess up with Bjork
Piss off Nulva
Get Joan's Surigram
Mess up with Sydney, Tobias, and Bernat
And lastly, get Charlie's Surigram.
Oh, thank you so so much!!! It's an unexpected but very pleasant surprise that I was responded to.
edit: Yep, I usually respond in around 10 days, just now realise that might have come off as rude, I'm sorry.
On another note, I FINALLY COMPLETED THE WHOLE GAME, WOOOOO, THANK YOU FOR YOUR HELP!!! The sadistic nature of the game, with it not having any saves or rollback, definitely made me hate my life a few times, but that's probably part of why this whole thing felt like I had to complete it XD
