A Knight’s Will: The first thing I noticed was the first three notes of your melody sound very similar to Donkey Kong Country. That adds to the nostalgic factor of this tune. There is a really nice balance in the upbeat and driven sections with the more calm and subdued sections to give a well-rounded loop.
Adverse Heights: The jagged walk down melody paints an image of a cold mountain musically. The high ostinato would also fit really well in the setting of an ice cave as well. It definitely gives off frigid vibes.
A Forlorn Palace: This harmonic minor vamp gives off a sense of evil or foreboding danger. This track stands out to me as feeling the most like it would belong in a gameboy game (they all would, but this one especially).
VS the Cold Sovereign: Great battle theme! I especially like the grace notes in your melody line. Good use of the prior themes and bringing them together in a culmination feeling like a satisfying climactic theme.
