This is really good! What I absolutely LOVE about this song is the use of directional sound to create this feeling of the music wrapping around me. I could really feel every little pluck and pull you put into the song in my right ear. Beyond that, the composition is great and very fun to listen to.
I wouldn't say this is super boss battle vibes, but it definitely fits the bill with Halloween, and I wouldn't bat an eye if it was in a boss battle.
Also I am pretty sure this song is having peaking issues. It feels like at some points certain instruments get crackly or sound like some part of their sound is dissappearing. If you could take a look at that, it'd be great!
Awesome job with this one, keep it up!
