I can only really get the ending where Psyche doesn't get to be with Eros/Or accepted and is alone... if I try to do something else, It ramps up the loneliness WAY too fast and then I have to spend a bunch of crunch time to ease the loneliness, and building up curiosity is very hard. Even on the third playthrough, when skipping thru all the dialouge, it feels hopeless to get a good ending.
That fast loneliness build up is intentional - it'll trigger a cut scene once it hits 100, and it can max up to 5 times without significantly changing the game (depending on the choices you make with the cut scenes).
To get one of the good endings, just focus on keeping your curiosity stat low and pay attention to the choices you make during the loneliness cut scenes. :)
