The game can be played in a web browser, on a smartphone, or using any VR goggles. To create it, we used two gaming engines: the browser and mobile versions were built using the Unity engine, and the VR version is based on the Unreal engine.

The Time Travel game is an interactive lesson created for the Museum of Second World War in Gdańsk based on an exhibition for children. As you move through the apartment and a classroom, you complete tasks and listen to and watch stories told from the point of view of people living throughout the WWII period – from 1939 to 1945.

You can play the game when visiting the Museum, on the Museum’s website, or on your mobile: on iOS and Android devices.
