The message contains a link: https://alfredvalley.itch.io/brute-fort-bonus However it requires a password. I've looked through brief spectrogram analysis of all of the tracks and haven't found anything but i might need to look harder in dungeon drone. Other than that i haven't seen anything in the manual or PNP sheets. (edit: upon further inspection nothing else seems to be hiding in the soundtrack itself, password must be elsewhere)
The only "notable" findings in the spectrograms are these. i assume the first one is some gibberish but i have no understanding of the significance of the second one. Both are found in dungeon drone.
