💧 Water Cycle Valley: Rain, River and Lake Diorama

Turn the Sun, climate and wind dials on a low-poly 3D valley and watch the water cycle: the lake and sea breathe out vapour, clouds climb the mountains and rain, streams run to the lake and the village tap. Plant or cut trees, keep the tap clean, and check that every drop adds up.
