Cube & Star: An Arbitrary Love

Cube & Star: An Arbitrary Love is a sandbox exploration game with a set of "structure" goals (Find the Ancient Star, Color the world, Unearth all of the relics etc) - and then a larger "shape the world in your image" goal which is more self-directed. As you color the world - the emotions and behavior of all of the entities shifts and changes. Source: The Game Website.
