Arguably limited in replayability, but so, so good - can't fault much about it other than the occasional navigation headache, and some of the objects you can interact with lacking enough feedback as to what they actually do/potentially trigger in your near vicinity. That said, your character basically spends the entire game as confused as you are, so at least it's narratively consistent!

Otherwise, it's the well-treaded Frictional/Amnesia thing: discrete chunks of anxiously evading things you don't want to look at spliced with exploration/world discovery in a horrible, dark place. Oh, and this time you don't have to mess around with fuelling the lantern.
