Video games that
make a difference

We develop and design video games, interactive applications, and engaging experiences with a measurable impact – educational, narrative, emotional, or anything in between. By partnering with universities, museums, public institutions, and private companies, we synergize skills and knowledge to make the world a better place.

A game for kids and young adults to discover and learn about musical instruments. It’s designed to spark creativity and interest in a playful way. The game is completely free to play on PC, Mac, iOS, and Android. It was developed in cooperation with media pedagogues and experts from the musiculum in Kiel and has been nominated for two TOMMI awards.

Together with the Museum Friedland we developed a gamified app that guides visitors through the border transit camp in Friedland. The app guides visitors through a wealth of information and materials in a playful manner. The multilingual project included the development of an interactive web presence and culminated in the creation of two board games.
