""she makes him a machine that allows him to relive his memories and see how different choices would have affected the outcome of those memories""
I have a doubt, so the choices that are made in the memories will affect the present? (because from what I understand in the overview it would simply be to see what result would have been if the Mc had chosen another choice?)
Leaving that aside, dev it would be nice to know waht tags/content you have planned for the game, and if the kinks/fetishes are going to be avoidable (they don't happen in the story according to player choice) skippable (they happen in the story but the player doesn't see the scene) forced by plot?
Thanks, good luck.
