Windows only for now. Linux/Mac coming soon but apparently they ran into trouble with those versions and need a little more work. I was able to run it in Proton by changing starship.cfg.json to this:

"Window": {
        "AudioBackend": "sdl",
        "Backend": {
            "Id": 1,
            "Name": "OpenGL"
