There was an indie game made in 2011 that you may or may not have heard of. It's called Sword and Sorcery, and the game was made with heavy focus on the music. It has a sort of epic chiptune style with hints of ascoustic.
I think you would particularly like the tracks "Dark Flute", "Lone Star, "The Prettiest Weed" , "Com64" , "Death To Everyone" , and "Confronting The Wolf". Sorry to bother if you're already aware of it.
Here's where you can buy/listen to the album: https://jimguthrie.bandcamp.com/album/sword-sworcery-lp-the-ballad-of-the-space-babies
