Build a factory with only a tiny amount of space given to you; 128x128, a whopping 16,384 tiles! Ores are limited in size, but have virtually infinite yields. Try to squeeze as much resources from them as you can.
This scenario map is inspired by the recent influx of tiny factories within the Factorio community. (Now with a constrained area sized for people with power-of-two-syndrome. It's also chunk-aligned!)
