I really appreciate and adore the sound design for Hex Casting, but one thing that stuck out to me was that the ambience that plays when you're casting a hex never changes.

But it would make sense if it changed after you were enlightened. Wouldn't shattering the barrier of your mind have some impact on such a thing, if even only your perception of it?
I'm not suggesting much (I don't think so, anyway; I don't know what workflows y'all have.), but it would be a really cool and haunting touch if the casting ambience changed from the well known humming to something approaching a melody.
