Fallen London is all about the impermanence of death in the Neath (the enormous cavern below the earth where cities get sucked into when they 'fall').
But this story follows a strange assassin who uses frogs and somehow manages to permanently get rid of people.
It ends up being quite charming. Here's my score:
+Polish: It worked smoothly and seemed well-thought out. Pretty much all Fallen London content is polished.
+Descriptiveness: I played it months ago, but I still remember the frogs and the (Spoiler - click to show)factory that threatens their wetlands
+Emotional impact: As I said it above, it's charming. Johnny Croak is a sweety.
+Interactivity: I definitely felt like I could make real choices.
-Would I play again? You can pay to replay (or play for the first time if you missed it) Fallen London's exceptional stories. This one was fun, but I wouldn't go out of my way to play it again, especially with some other very good stories out there.
