Fireflies is a horror adventure centered on Riario, who travels to the village where his grandfather once lived after receiving a letter asking him to find and publish a journal. The premise begins as a family mystery, but the village’s history turns it toward darker discoveries.
As Riario reads the journal, he learns that his grandfather belonged to a satanist cult and recorded dark rituals and his life as a cultist. The game describes itself as a puzzle-filled adventure horror, with the search for the journal and its meaning anchoring the story.
The village’s sacrificed spirits survive as memories that haunt Riario, giving the setting a supernatural edge. Fireflies is inspired by Amnesia: The Dark Descent, placing its investigation within a recognizable horror tradition while centering its own story on inherited secrets, cult history, and the traces left behind in a village shaped by its past.
