This is a good suggestion, thanks. I wanted the conversations to feel "organic" which is why I haven't added any mechanic like this. But you''re right that people be unaware they're missing content. So I'll have a think about this & possible add something. Thanks!
I think just a little "map" menu where you can jump back in at the conversation point where a day branches would be good. Kinda rough replaying the entire day because you feel like maybe something different could have happened.
Or a gallery section which shows how many pictures are in each day. That way at least you know you missed something and it's worth going through again!
