i really like the music for this game, it reminds me of song but i don' remeber which one it was, i don't know if you get which one i mean jaja.
The music is made by Marlilo, he is an excellent composer! If you're talking about the boss theme, Marlilo's sound is heavily inspired by Terraria music. That could be what you're thinking of in terms of comparisons. Check out his SoundCloud (https://soundcloud.com/marliloo)!
