hello. try loading this page - https://sciencevr.itch.io/covid19 and you should see a download button for the APK file. Then you can drag it into SideQuest to install to your Quest/Quest2. Merry Xmas!
The "Download Demo" button for "ScienceVR-COVID19-quest-v0.z.apk" is the paid version then?
Sorry for the confusion. The bundle is to fund further development and this is the currently available version.
