Hi Charlie! Was not sure if you'd find the link in my Unity Asset Store review! Awesome to see you got here! :D
Super glad you enjoyed the game! Thank you immensely for the music! Even though we did not use it for a 'hero's journey' adventure game as you envisioned, we hope we did it justice.
Best of luck in your Sound Designer journey!
ps: Thank you for mentioning us in your website ;)
