About the game
Light Source is a gloomy two-dimensional RPG built on turn-based fights. You guide Bulb as he works to bring brightness back to Lumeria, a kingdom sunk in shadow. Along the way you assist its inhabitants, face tougher and tougher enemies, and learn what lies concealed in the crumbling land. Left Marino developed and published it, and it was released in 2026.
