PlayNewtAquaFlow is a free cozy idle city-builder released on itch.io on October 26, 2026, about the part of a city nobody sees: its water. Take water from the river, clean it and pipe it to every house, then carry wastewater away, treat it and send it safely to the sea. Every house you supply pays you, and the town keeps earning while you are away.
