HUHHH wait!! whats the true ending?
Pretty sure you have to get all 8 endings first, but after you get them all, go back to the beginning where you enter Milo's nickname, and enter "love" as the nickname. It'll proceed from there. There's two choices (so kind of like two endings actually), and they lead to different dialogue and outcomes - one of the choices (I believe it's the first, but it could happen with either choice possibly. I'm not sure) will cause you to lose all your saves and endings.
What I did is I chose the first option, and then, after losing everything, I just hit skip throughout all the options to get all eight of the endings again. Then I went back for the second option. So that way I could see both. If you wanna see them both without all that work in the middle, then I guess you might wanna pick the second option first and then go back for the first option, but I'm not sure if that's how it works.
