i'm really fascinated with how you chose to approach composing your tracks musically; they're all very cohesive and yet they manage to stand out from one another with subtle changes in melodic content. ^^ my favorite may be "Death"; i think it's because of lighthearted it sounds despite the track name, which is likely due to the triad of tracks using similar pitch limitations.
i think it'd be cool see how you'd craft distinct lead melodies that try to expand as much as they can within the notes allowed, to properly express the ideas you had in mind!
