The complete implementation of the Backseat playground prototype was tested for the first time on Monday the 13th of March. The experience was very promising. When leaving the built areas of Lidingö, we directly encountered howling wolves in the woods. When we reported the event back to the field agents’ central command, they called us back and discussed what to do. However, we also encountered technical issues with the stability of the game, which has to be adressed before the user evaluation.
