This entry is a serviceable addition to the Lovecraft universe, although it stumbles over some common challenges that plague initial releases.
The story visits standard New England locations that are central to Lovecraft's work, and design choices support a creepy atmosphere. Presentation details, like the custom background and buttons to choose your next action, are a welcome departure from Twine's black-and-white defaults.
The investigation that leads the narrator to Innsmouth is much less exciting than time spent in the town itself. Early pages end with the equivalent of "click to continue" buttons, and every possible conversation option must be exhausted before doing something else.
(It made me feel less like a sharp-eyed detective and more like a bored student hearing lectures that repeated the same few ideas about Innsmouth and its sinister residents.)
However, it's evident that the author's skills were honed during the process of developing this work. My experience in the town of Innsmouth was briskly paced and full of enjoyably tense decisions. There are multiple ways to encounter plot points before fleeing to safety, and although bad decisions can end in disaster, the author allows players to undo their mistakes.
