This could have been just a middling walking simulator if not for the setting. It's clear the creator started out wanting to build a 3D 1940s/1950s era rural town and then built a game around it once the simulation was finished, and, honestly? It benefits a lot from it. It's genuinely a lovely and fascinating place to explore, and the otherwise pretty middling Ethan Carter/Gone Home walking sim ghost story is elevated just from being placed within this very lifelike setting.
