I was unable to launch this in Ubuntu 20.04.2 LTS. There was an error about a missing .pck file.
Error: Couldn't load project data at path ".". Is the .pck file missing? If you've renamed the executable, the associated .pck file should also be renamed to match the executable's name (without the extension).
I'm not sure but maybe the .pck wasn't embedded or it was renamed? Anyway the soundtrack is great! Thanks!
