An AR Care Game about ecology, where you meet a being from an unknown place. You help them survive in their new environment while asking yourself questions about our relationship with nature. This project is a mobile game using augmented reality to propose an experience happening in real time and space. This game is about taking care of a lost being: you help them by setting up a new ecosystem unraveling around you, suited to their needs. You talk with them, build a relationship, discover where they come from and help them go back home. Like Candide by Voltaire, you see the world through the eyes of a naive character. They will raise questions about paradigms of our capitalist societies, its impact on the planet and on ourselves. This game invites a young audience (10 years and up) to ask themselves about ecological issues, and imagine new desirable futures.
