New tile placement game Preserve has a cool theme: Build up flourishing ecosystems by dropping down water, plants, and animals to form environments within your larger biome to sustain ever-more-complex ecosystems. It's set up as a puzzle because everything you place has a symbiotic effect on everything else. Bees and flowers need each other, as a very simple example.
"Preserve is a relaxing puzzle nature-building game in which you flourish a vibrant ecosystem by cleverly placing plants and animals," says the developer.
