The world is facing an environmental disaster. But not all is lost. The young, and not so young, are about to receive help from a powerful being from another galaxy: Elva. Elva is a small dragon with immense powers, who has arrived on Earth to teach us how to take care of the planet. Starting with the most basic tasks, such as cleaning the garbage, and taking it to be recycled, or sending it to a ship or plane to be processed, to planting trees, regenerating fields and forests, cleaning the sea, freeing marine animals, or saving injured animals. We also defend forests and homes from fire with the power of water. Elva is an educational game, which wants to teach the values of caring for our planet. It is a game, but with a message: we can take care and save the Earth. With the help of Elva, and with a little effort from everyone.
