I can't playtest the Linux version so I dug up a comment from a guy who had trouble extracting, he said this "It seems that if you do it graphically it does it directly, but if you use console it first extracts .bz2 and then you have to extract it from .tar"
thank you i realized what the issue is now. Could you rename all future linux download files as tar.bz2 instead of just .bz2? since its a tar file compressed with bz2 and not actually just a file compressed as bz2. That way someone can just extract the file using tar -xjf lustful_sin.tar.bz2 for example
