As odd as the "roguelike" set up is for a Frictional game, it actually works pretty well. The scares we're kind of hit or miss in these games after the first Amnesia, but this kinda works. Very similar to how the alien in Isolation works, it stalks and appears based on how you react. And how you react is based on your supplies and goals. Despite a pretty weak end sequence, partly because it bugged out and failed me on an optional objective, it's pretty solid.
The story itself is serviceable, if not confusing. But when your story relies on picking up notes, and remembering names, dates, plot evetns, its hard to follow. I'm sure reddit has it all explained thoroughly, but sometimes I like the plot to be relevant to what I see before me.
