Explore the derelict fulgoran ringworld of Ribbonia, an artificial planet where spatial reasoning and creativity are the key to your survival. Can you handle C.H.A.R.L.E.S., the crazed and lonely AI? Discover forgotten Fulgoran crafting techniques involving fusion plasma, molten plastic and dive into Factorio nostalgia on Ribbonia. Ribbonia minimally affects the vanilla game and can simply be added to existing saves.
