The developer's depressed? That's the least interesting thing to learn about anyone. Depressed people promoting their depression sounds disingenuous.
Not to be all negative, for walking simulators with no interaction but nice dreamy atmosphere, try Liminalcore. Relaxing and calming, great on an ultrawide OLED. Lots of vast shadow areas. Huge scale architecture. Bump the FOV setting up a little from default. No cheap gimmicks, just a restrained dream world with subtle hint of something lurking in the shadows. In terms of artistic walking games, this is one of the good ones.
