Thank you very much, man. Yeah, we basically played everything that was in the original in the first and last sections; it's a very short, very simple piece in the game, so in between there we decided to make it a bit heavier and introduce a few lead melodies. I think the original is a really nice, kind of haunting lead in to the rest of the game, where the music is much more upbeat.
But yeah, man, I am definitely open to the idea of collaborating. I've actually been thinking it would be cool to try to do a community-wide Fringes project, where we could round up everyone who wanted to join in and do a community cover song. Even everyone who doesn't play music could be involved in the song selection and editing process (or do artwork for the project, and that sort of thing). It could be fun!
