Great atmosphere in this game you did an amazing job at it :) I wish more developers around here would be this good at it, sometime their stories are amazing and all but it lacks this something that would make it unique and more vibrant.
Also, I wished for a rollback button at first but in the end, it's not a real problem and it even pushes the player to be way more careful and attentive to the story and dialogues. With Ren'Py(for me at least) we're rushing through dialogues and if we missed something important we know we can just rollback and all but I think it's not how it should be.
