Disclaimer: might not work on Linux/MacOS!
I'm still fighting with Linux compatiblity. I'll see what I can do.
I tried using the itch app to install, and it worked fine, so I guess it was down to me not understanding how to install and run ViCam on its own.
I think I would've had to do "chmod +x" on the file in terminal, rather than try to get "Run Software" to work without doing that.
