Description (written by the developer; not a statement by this register)

Assembly Line is a factory automation builder. Mine ore with drills, carry it on conveyor belts, smelt it into plates, and let robot arms feed your machines, so every line you build keeps running while you plan the next one. Start with one drill and one furnace on empty grass. Add drills, split and merge belts, fix jams, raise steam power, and research bigger machines in the lab. Update 2, Oil Era: strike crude with pumpjacks, pipe it to a refinery and a chemical plant, and make plastic, sulfur and advanced circuits. Electric furnaces, modules, accumulators, pollution and scrubbers. Save any build as a blueprint and share it as a string. Build alone or open your factory to friends with a join code, and race the leaderboards. The camera looks down at a fixed angle, so your whole factory reads at a glance. Your factory saves, so come back any time. Join the Flatworks group for 1.25x factory speed. A new code every Friday on the home screen.
