The Square

by mmmatt

The Square is a Factorio challenge mod where your factory begins inside a tiny square and can grows by researching Square expansion. Each square expansion level adds one buildable tile in each direction. The intended purpose of this mod is to constrain space and force efficient design of the factory.
