Gameplay changed little from previous entries, with mostly cosmetic changes (e.g. Rosa now uses her cellphone instead of a computer). Combining notes is once again a thing, used just in the right away: it's neither the only thing you need to do, nor completely forgotten. Puzzles were nice too, though, as another reviewer mentioned, one of them was a bit too obscure.

The story remains the strong point, especially in how each game stands well as single entry but still gives us glimpses into the overarching story connecting the Countess and Madeline to Joey and the Blackwells.

There's a particular development I find very interesting. Blackwell Legacy ends in a weird expansion of the fantasy elements of this storyworld, adding sin and demons into what was till then a world in which death is morally neutral. It was a jarring ending because of how nothing in the story had hinted at that sort of thing. In this game, we are slowly primed to the fact Gavin is doing something very creepy, so the revelation that he's some kind of lifeforce leech who lived for more than 200 years is much more successful.
