The January 2019 version is here. We have fixed several issues in this new version.
Several users told us that they had a black screen, with only the 3D objects displayed. Others warned us that the GPS prevented them from playing the game. After a few searches and several tests, we realized that the authorizations were no longer displayed at the first launch of the game.
We redesigned the way these permissions are handled. With Unity 2018, permissions are no longer automatic and must be added manually.
This caused many problems, please excuse us for the inconvenience.
Important: We have decided to remove the GPS completely, because we think that it poses more problems than fun in the overall gameplay of the game. So there is no need for localization to play Walk & Slash.
The only authorization required is therefore the camera.
