About the game
Circular Fallacy is an indie RPG that shifts fluidly between two-dimensional card mechanics and fully three-dimensional settings. Its story follows a narrator whose entire world vanishes while rain falls without pause through the night, pushing them into a search for answers about their own identity. Unstable Matter both developed and published the game in 2025.
