Hi,
We have uploaded a new Linux build. We're unable to test it (no access to Linux machine). If you decide to update the game to try it out, please let us know if it works ok!
It's not on your end. It just locks up on a black screen after the photosensitivity splash screen fades out, hogging up some 85% of my CPU (Ryzen 3700x) until I kill the process. I did leave it running for a couple of minutes in case it was just precompiling some complex shaders or something, but no luck. Couldn't get any useful debug output out of it either. I guess I'm giving up for now.
The game looks like something I might enjoy, so I'll definitely keep an eye out for updates. Let me know if I can help with testing.
