Pretty intense but not quite intense enough to be a final boss I think, maybe the big mini boss a chapter before the final.
Also for a loop to fade out like that doesn't really sync up too well, but that's an easy adjustment.
Hm, interesting take on it. I'll keep that in mind.
As far as the loop, that's just the song looping back and then I faded it out, I did render separate files which are actually loopable (which I've been doing for all of my RPG tracks thus far - generally, rendering out separate files for intro and loop, as WAVs to avoid any gaps inserted at the beginning like MP3s tend to do).
Please contact me if you would like to use this in a project. We can discuss the details.
