I've played for more or less 20 hours of this now after seeing it recommended everywhere for like a million times in the past two years. It's a very relaxing game like advertised. Or incredibly stressful, depending on what kind of thoughts enter your mind when you can play a game without having to think about what you're doing all that much.

The premise is very relaxing though. Clean up dirty environments. Very fun to see the end result when you're done, and there is lots of content for it to not get repetitive. Mod support would have been nice, but looks like that's not coming for this game.
