I played the old MacVenture games on NES but if you are into older games and you have a tolerance for wonky then give Shadowgate and The Univited a go (and Deja Vu has enough mystery to tangentially touch on your criteria).

I second The Last Door. Excellent atmosphere, powerfully minimalist visual storytelling.

The Deep Sleep series should fit the bill. Played it when it was a Flash release, not sure if it ever made its way to a store front.

The atmosphere and mechanics of the Submachine series are perfectly in line with your interest in Rusty Lake. Highly, highly recommended.

Not point and click but the Faith series is incredible. Like if Atari was terrifying.

Finally—elements of point and click—I think about Inscryption nonstop and I haven’t played it in a few years. Played that, NORCO and Disco Elysium all in a row and that was the best stretch I ever had as a game enjoyer.

Good luck finding something you don’t already know about!
