An economy game where the real work is invisible: 22 game systems mesh together — market, power, research, workers, contracts and two restart layers with their own rewards. Ten ore tiers lead from stone to uranium, and the operation keeps running while you are away. On top sits a deliberate amount of spectacle: counting-up numbers, a living mine shaft and a spotlight intro that shows you where to tap next. Anyone who wants less motion gets it — that consideration sits in 25 places in the code. Save games can be exported and read back in, and once installed it runs like an app.
