The ambient nature of the intro sets the space well for the Hallows area and sets the mood for a great boss fight. I absolutely love when the bass comes in and is bouncing back and forth from left ear to right ear and back. This is such a creative way of demonstrating the mind games that you reference in your description. The acceleration of the drums makes it feel like we are kind of sliding into the battle as if we didn’t realize that it was a battle at first. My second favorite part of your composition (after the panned bass notes) is the warbled cluster piano notes that come in at 2:15; this is such a cool way to show chaos and more mind games! While there is not a melody that I am left humming at the end, I think that is super appropriate for this type of battle track. What I was left with at the end was a feeling of the atmosphere of what I just heard - I felt like I was in the mindscape. This would be very cool in-game! Overall great work and thank you for sharing!
