This game is SO detailed for a free game, wow. 8 main endings, the option to choose a cute (or silly) nickname for Milo, one true ending (with two variations), even three secret cutscenes in the load page that show up based on the route you're on?! And easter egg references to other VNs (a lot of which are games with yandere style characters, just like this one). Plus the art style is very cute (and so is Milo, can someone please save this poor cutie from the main character, omg).
I also just found out there might be some more minor little updates and additions in the future? Holy cow!
Great game, 10/10, cannot recommend highly enough!
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.
