Welp, you got me to listen to this piece multiple times so I guess I know what I'm putting down for listenability ;)
I'm glad to see music being created with procedural components in mind. I think it'd be fitting for games like a walking simulator as you've mentioned. It's nice to have a little bit of variation if I'm exploring one place in multiple instances, or over one long period of time. I remember reading that No Man's Sky did something like this with their OST.
As for the piece itself, I feel that you've put something together that's solid and fulfills its purpose really well. It sets the vibe for a setting like the image in this submission, and lends itself well for other sounds/melodies/etc. to come in and give the listener (or the player) something unique to listen to.
Hopefully you continue experimenting with this tech - there's a lot of games that could benefit from this!
Thanks for sharing, and keep up the good work :)
