>>7827108It's not exactly like what you described, but a year or so ago I had a hand in making some concept art for this game. It's a walking sim with liminal spaces focused around an empty mall.

I'm just a freelance artist, so I didn't have any hand in making the actual game, but some of the environments I concepted got re-made and turned into actual game environments. Pic related was one of the concepts I did.
