Field notes
Players place houses, people, trees, and berry bushes, then test materials against rain, hail, tornadoes, earthquakes, and meteors. Residents gather food, need shelter, and cannot cross cliffs or walls; material behavior is explicitly described as playful rather than scientifically accurate. Undo keeps up to 12 actions, including map changes and loaded games, while world files can be downloaded and imported as JSON.
