Hey ADR3-N it's good to see you active here!
I like this A LOT! Feels like something straight out of pre-2015 Newgrounds (the best of days for gaming), which is actually just what I wanted in this moment. I'm really happy~!
So, um... the best part of the song is probably that chord sequence at around 2:04 and then lasts another minute. Always big for those magical chord progressions (actually working on a song with one right now).
A couple criticisms though: One, this does feel a bit too long. It's not really developing enough by the end to warrant being that long in my mind. Two, why was this called a Gregorian house song? It didn't feel too ancient-y to me (for the record something like: https://www.newgrounds.com/audio/listen/1015214 is what I might call Gregorian).
Beyond that this is amazing! You deserve me to give your vocal stuff attention, it is why I gave you that friend request after all~. :D
