Stop installing the apk on mobile you dingledorks
Its for VR and you use mobile app station to install the app
If you dont see the prompt to install it anywhere [and it just darkens] then install cx file explorer and allow it to access your files and to install apps [https://cxfileexplorer.com/] or use sidequest on pc if you have that. Use CX File Explorer to install gorilla tag horror. To update it just install a new apk i guess
