About the game
Players sit down on a cozy bench deep in the woods and strike up a conversation with a being older than the world itself. The adventure reveals where demons dwell, what a human is capable of doing to them, and, most importantly, what their hearts taste like. Jiabisu both developed and published the game in 2020.
