I'm still looking forward to this game, more so now as I really like Storm's Theme and the look of the game from the video.
Now, I know you said that the Battle Theme was still only Beta, but I have some issues, I don't like how it sounds rather slow paced to me, when I get into a battle, my thought is "Oh shit. monsters KILL!" and that music doesn't seem to really reflect it, it seemed more like a Theme Song at the beginning, and I think it should be sped up to a faster pace, but ignoring that, it's still a good song.
