Evolites

Described by the game developer as "Evolites is a simple life simulation where you indirectly control the fates of a countless number of tiny, unique creatures, known as Evolites. As the Evolites evolve naturally, various tools are at your disposal to save, destroy, create, and interact with them. You may let things run their course, or you may directly intervene, and make sure that only your chosen strain of Evolites survives!"
