I thought they were interesting I just expected them to help things click a little more! They felt more like largely only supplemental lore without all that much in them that I could connect back to what I saw during the game, particularly when it came to the description of the badgers guilt. Especially since I found myself very confused as to how the images presented were supposed to lead players to conclude the badger to be the killer, I was hoping that upon reading his ending short story this would make more sense.
I think it's something about the mud and the prints because I did notice that the badger's boots went from nice and clean to a mess, and the last frame does have some hefty footprints. BUT I did only figure it out after going over the images, after guessing everyone else and then going back when I knew the killer. That's just my theory on it tho.
