The Gamer route seems to have two similar endings, but it's not a big deal if you count it otherwise. It was just surprising.

Sorry about that >.< That's about as good as it gets for everyone in this story :( To be honest, originally, I wasn't even going to have that as an ending, I was going to make every single ending a bad ending, but that felt toooo mean, haha. But yeah, it's supposed to be a bittersweet story, unfortunately x3 Technically, a part of Kuro is always gonna live inside Shiro though :3
However... I plan on remaking the game entirely at some point in the future with new routes and new art and stuff, so I might put in one or two much happier endings when I eventually get working on that :3
Thank you so much for playing!
