im sorry i dunno how to help... are you sure you got all endings? maybe you missed something? what version are you playing (sfw/nsfw)?
Nsfw. I was wondering if I have to like finish it all in one sit through of the game so to speak. I tried to keep track of all the routes as i completed them. I might bite the bullet thought and just try all the endings again see if that works out. Thank you for trying to help though i appreciate the effort you went through.
