Greetings.
Actually, it's a free and open-source package. The package will include quite a few tracks, so I'm not sure if it would be feasible to distribute it as an uncompressed file. If I remember correctly, itch doesn't allow files larger than one gigabyte.
In any case, I'll examine the FLAC files (I'm not very familiar with them).
You're right that the best thing to do is distribute the files uncompressed and then have everyone convert them to the format they prefer. I assume everyone has the resources to do that.
Thanks for your perspective.
