[Played on SteamDeck (verified), batterylife wasn't great, but it ran perfectly and I had no issues with it.]
The best part of the first two Amnesia games, in my opinion, was piecing together the mystery alongside your character. I unfortunately didn't have this same experience with Rebirth, I figured out nearly the whole "mystery" not even half-way through my playthrough. The atmosphere was really good, the environments were interesting, puzzles were a mixed bag, and I liked the monster designs. Overall it's not a bad game, but I'd rather play the other games in the series to be honest.
