It's not really Dark Fall 2
If you're expecting Dark Fall 2, kill that expectation now. The only thing that ties the two games together is the appearance of a minor character from the first game. Other than that, there's no connection, not even in terms of genre.
Dark Fall was a straight-forward ghost story -- paranormal happenings and the like. This one starts off like that in an abandoned lighthouse. The ambience is spooky and there's plenty of tension and thrills. You think you're in for another ghost story, another Dark Fall game. This expectation is fed through the use of the term "Dark Fall" by characters and writings during this beginning portion of the game as well, so it's easy to expect a struggle against a similar dark, spiritual entity yet again. However, this is soon derailed as the plot seems to jump tracks and begin to follow the course of a sci-fi adventure.
What you first perceived as a tale of a haunted lighthouse ends up being a time traveling adventure with a confusing and abrupt ending. In fact, the entire plot causes more confusion than resolution. It's hard to put the pieces together and determine what was paranormal and what wasn't, or if anything was in the first place. You're only left with questions of "how?" and "why?" It's sorely disappointing, and the jump from ghost story to science fiction is the reason why I wouldn't label it Dark Fall 2.
However, the artwork and sound design are still fantastic, following the high standards that the first Dark Fall set. It's very engaging to view and interact with items from the early 20th Century, and all the rooms are laid out in a pleasant manner. Reading journals of the different characters and the other reading material encountered is engaging. Boakes certainly has a talent for characters and setting, and there was no disappointment here.
In short, the atmosphere measures up and is immersive, but the sci-fi plot feels disjointed and gives no strong resolution in the end. I'm glad I played, but it was disappointing.
