Cave Factory

A 2D side-view factory builder where every grain of dirt, every drop of water, and every wisp of steam in the world is its own simulated pixel — the way they are in Noita. Dig downward through a 500x500 tile cave, trigger landslides, melt ice into water, condense steam into snow, pool liquids around the base of your furnaces, and watch dirt pixels pile up into brand-new dirt tiles when enough of them collect. Underneath the sim is a real factory game. Mine ore. Sift dirt. Smelt iron. Quench molten iron into steel at exactly the right moment. Lay conveyor belts and inserters, build chests with input and output sides, and grow a vertical factory deep into the earth. A tech tree gates the late-game machines and recipes — you earn the dirt sifter, stone furnace, input chest, magnets, inserters, and more by playing your way to them.
