Well...
This is a very interesting hybrid between your earlier 2005-2006 style and your more polished 2012+ style, it's almost like a symbolic pick to coming back after all this time haha!
I can't really compare this song to Surface because they just don't feel all that similar (maybe if it had more SE like the ones Surface had on it's intro? I don't know), they feel similar but it's more a "yeah they're the same genre and made by the same guy" kinda deal, but it manages to work great as a standalone song anyway so it's not really an issue.
My main criticism is that most melodies on here aren't as memorable as in other songs, and as such this track feels a bit... boring and forgettable compared to other things you've done before (and I mean, stuff like Cerebral Infection was also a fast paced creepy boss fight song and is much more memorable than this, so this is not "it's dark so it's bad"), even though the dynamics are great (much better than anything from 2005-2006 that's for sure) and the mixing is surely better than anything I can personally do, so I really don't want to call this song bad, but I don't want to get all "THE GUY WHOSE MUSIC I LOVED IN THE 2000S IS BACK SO THIS SONG IS PURE PERFECTION" hypey either because you probably have gotten more than enough of these comments. I guess after almost 7 years I held you to a much higher standard.
TL;DR: Good song, interesting mix of styles, the melodies aren't my thing though, but great use of dynamics and mixing anyway.
