Factory is a simple factory-builder game that runs on a Teensy 4.0 connected to an 84x48 pixel Nokia 5110 LCD screen and 6 buttons. You can also play it here, compiled via emscripten.

Your goal is to build a factory that automates the production and consumption of science. Find patches of ore and mine them. Open the menu and navigate to the crafting tab, marked "+", to view recipes and craft items. Build furnaces and place them by selecting them from the inventory tab, marked with 6 dots. Insert resources into a furnace by facing it, opening your inventory, and dragging items into the furnace's inventory. Insert iron or copper with coal into a furnace to produce iron and copper plates. Build drills to automate mining when coal is inserted. Build assemblers to automate crafting. Build belts to automate the logistics of moving resources to where they are needed. Use splitters to distribute resources equally between multiple belts. Use crossings to cross 2 independent belt paths, so items continue in a straight line to the next belt. Build labs to consume science. Finally, build as much science as you can and feed them into labs. Automate as much of this as possible, finding new patches of resources to use as the old patches run out.
I build a battery-powered handheld device that runs this as a birthday present for my Factorio-loving brother. I barely finished it in time and didn't take any pictures of the final result before giving it to him.
