Agree this fits while in a menu or inventory. Or after a fight. Nice guitar!
I don't think it'd fit a boss fight, but rather an introduction theme to a boss maybe. It's pretty quiet and could definitely use a volume boost, and I feel like the drums could be quieter and the 8-bit synth in the background could be louder. It loops seamlessly though, so well done on that. Overall, it feels a bit "generic" to me. There's nothing too big or interesting about it. But nice work anyways.
Very nice man! Love it! :)
