Thanks for letting me know, sadly I didn't have time to test it on a Linux VM, and even less time to fix it. I'll take a look after work tomorrow if I have time.
It worked on arch for me. Make sure to have the .x86_64 file and the .pck file in the same folder, set the .x86_64 file to executable, and run that one. Should work on any non-arm linux distro, so if you’re on arm, you’re out of luck.
