In my 6 months internship at Step in Books I worked as a gameplay programmer for Mur.
Mur is an AR mobile game which recently won the Bologna Ragazzi Digital 2017 award in the AR game category. I was responsible for design implementation, the camera system (a hybrid between gyroscope and touch gestures) and profilin/optimization for both Android and iOS builds.
Development of the Mur app has ended in March 2017, and is expected to be released soon on the app stores.
You can find more information about Mur in the official website.
