Really interesting song indeed. Overall the song seems to be somewhat unconsistent so I guess it could be difficult to like the song as a whole but there definitely are some parts that I really like. Those parts with the strings and the choir create an awesome atmosphere and remind me of an old dos game: Heretic.
The beginning of the song was quite distinct from the rest of the song and seemed to contain some interesting rhythmic stuff. It was all right but I didn't like it as much as the rest of the song. Still overall pretty nice job!
