I listened to the first 4 tracks, and skipped around the rest to get an idea of the content. Lots of good stuff!
Great job mimicking the tone of Hades’ music. It has a fantastic OST. Korb also wrote Bastion’s OST, which is worth a listen, too.
In your soundtrack, I think there needs to be more balance between the “wall of sound” harmonies vs. lyrical melodies. IMO, the best game soundtracks are the ones you come away from humming a theme, and I struggled to find one here.
I think “Through Asphodel” is a good example - melody kicks in about 2 minutes in. From what I heard (which wasn’t everything, admittedly), you have the background metal sound figured out, but I think you’re missing that soaring melody in some of these.
