Ghostfinder: Shift is a truly professional piece of IF. Set in a consistently well imagined and thought-out world of shifters and ghostfinders, the story features the player as an occult investigator trying to solve a string of horrific murders.
As with the world building, the writing is on a professional level all the way through, and meticulously detailed. With access to case files and your order’s private database, a choice IF interface allows you to draw connections and approach the identity of the killer. As such, the choice mechanisms here function as a way to solve the puzzle, rather than navigating a branching story.
Every aspect of Ghostfinder: Shift is impressive, but even though the puzzle aspect was well done, its writing is where it truly shines. However, as with every genre work, it does cater to a niche audience. I can easily picture a Ghostfinder series of novels in the adult urban fantasy section at my favourite book store.
