Depending on your system, either libbert.dll (on Windows) or libbert.so (on Linux) is not loading. Try to verify to see if one of the file is in the app's directory. Also:
- Which operating system are you using to run the app? If you are on Linux, make sure to run "satania-buddy.sh" instead.
- Are you trying to run the app via the itch.io client? I honestly never tested this, so it may not work correctly.
