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.
