This game is literally "Return of the Obra Dinn" merged with DnD mechanics. You got every possibilities to understand who they are and what happened to them (there's even options that don't appear). And the only way you can find out isn't by brute-forcing, since there's so much options, but by looking at the details of each scene. And that's how good it is.
Also I loved these twists (didn't expect some of them tbh).
