This paper focuses on how to design a childrens game to help them realize that they can have a positive influence on the environment. We present a detailed description and analysis of our work process from brainstorming to the discussions after playtesting our prototype. Playing while learning has been the motivation of our work which is divided into three specific topics: How to involve the users in the design process, what type of social aspects exist in our game, and the importance of a feedback and reward system in the game. We look upon earlier research and examples within these three areas. We designed our game from a user centered perspective to make the users influence and encourage a discussion and awareness about environmental questions in a way that isnʼt negative. While designing our game we wanted to shed a positive light upon a serious issue and bring the environment into the topics of play and fun. In our research we discoverd that focusing on small subjects and tasks the children started to discuss the complex theme of the environment. We focus on the interaction with the children and using their influence to make decisions in our design process. Involving them helped us to see that there is not only one way of learning. In this game, the users learned from engagement and discussion, which ended up being the most important part of the game play.
