I made it in, like, 30 minutes, because I was really inspired (and drunk), so it may not be very well structured. Plus, I had problems with my software...
Well, as of the tune: it can be used as a loop, but I don't recommend it. It lasts 1:23 and I don't think RPG battles are that long.
Comment and rate, fellas!
Please contact me if you would like to use this in a project. We can discuss the details.
