Textorio is a factory automation game made entirely of text characters. You crash on the dead planet Kepler-442b with a wrist terminal and 50,000 colonists asleep in cryo below you, and the reactor keeping them alive is off. So you mine, smelt, automate, and dig down through four stacked worlds toward the core. The systems are real: electricity flows along grids that brown out, fluids have pressure, steam condenses back into water, and there is a pneumatic logic language you can build computers out of. It runs on almost anything. Free demo on Steam.
