What the title says. I'm not that experienced with Linux Systems, so I have no idea how to proceed to run this app. Some instructions would be really appreciated.
There are two ways:
1. Using itch.io App
Download itch.io App - https://itch.io/app
Go to the downloaded file properties and mark it executable, then double click it to run the installer.
Open installed itch.io App, search for the VTuberWebcam in the in-app browser and click Install.
Choose VTuberWebcam in the library and click Launch.
itch.io App can auto-update everything, most updates are just few megabytes,
so you don't have to download ~300mb archive again for the new version each time.
2. Run from manually downloaded archive
Download VTuberWebcam as ZIP archive, extract it.
Got to the vtuber_webcam.sh file properties and mark it executable, then double click it to run.
