Resting? What's that? I never heard of it!
Hey, love the song! It felt very cinematic, and the vibe reminded me a bit of Terra Battle's main theme, which is a total and absolute compliment! And yes, it's ambiented in an apocalyptic world lol So I totally see this working in the settings you described above.
I think you worked on the layers pretty darn well, and managed to keep it entertaining. The vocals add sooo much to it, if you ask me, they are the main dish of the soundtrack. It's what gives it the extra punch and moves up front during an scene! While then it can go back to wait in the background, acompanying the game.
Anyways, great job!
