I am a hobbyist developing a free fantasy-themed deckbuilder roguelike: https://alsoknown.itch.io/way-to-crown
Background music is half generic free assets, half contributed by different composers which I also found on itch.io. Current style can be described as ‘celtic ambient’, you can listen to existing tracks in game (choose from setting menu).
This is a free hobby project, so unfortunately I can not offer any remuneration, just credit.
If you are interested, your track can also be in the game. Contact me either on game’s discord server or directly: alsoknown1
