The company who runs a river port in Portugal usually has lots of school visits to its facilities. So, having that in mind, they wish to have a small app with a game so the kids visiting the place could play. The idea is to have a simple game (lets say Android only for now) with the following idea: The main goal of Douro’s app is to create awareness in young kids (under 12 years old) of the importance of having a clean, well maintained and navigable waterway (river). It should transmit this knowledge while having a fun and challenging tone – in a game format. The game can have fictitious design elements, but it should be complemented with realistic information and multimedia (like pictures) about Douro River, to fulfil its educative role.
