Electric Highways is the best walking simulator type / art game I've played. I first played it when I was a bit younger, and I've been replaying it ever since. It is simple and minimalist, but perfect in what it does.
I made a short analysis video of it, though it is primarily a love letter to the game. The themes and message I interpreted resonate with me strongly.
Thank you for making this piece of art, Zykov Eddy.
