The soundtrack is out!
So, a few bits of information: Steam by default requires MP3s to be provided. We encoded them in as high of a quality as possible, and also added the option for FLAC downloads. That being said, the FLAC is re-encoded from the original .ogg release. The quality of the original .oggs is more or less lossless, but there may have been some quality lost in the transfer between the different formats. Keep in mind that our music is largely sample-based and therefore using extremely lossless formats doesn't achieve very much, as the original samples are in pretty poor quality themselves!
The soundtrack will be updated as we add more tracks to the game. If you find a song in the game which is not yet included, it'll either be added in the next release or you can tell us so we can update it!
With utmost musical regards,
