A Zachtronics puzzle game about alchemy. You design machines that assemble potions, poisons and other products from basic elements.
How you code
You place mechanical arms and other parts on a board, then give each arm a sequence of instructions such as grab, rotate and extend on a timeline. The arms repeat their instructions to build the product. It works like visual programming, but it centres on building machines, which is why it is listed as borderline.
