Oppressive Gloom by Kevin MacLeod
Sorry about the BBCode below. I tried to remove it afterwards, but couldn't edit the comment. *facepalm*
I'm using this song in my game at Kongregate: [url=https://www.kongregate.com/games/RPSchmitt137/wizard-vs-orc-zombies]Wizard vs Orc Zombies[/url]. It's my first game ever, I hope it makes some justice to the song. :)
Your work is amazing, Kevin! Thanks for sharing it. Best wishes!
