I had a complete memory blank and for whatever reason mistook (the admittedly really good puzzle game) Antichamber for the Submachine series. No idea why! I agree, it's a really good series. Speaking of good series - I am a Twin Peaks fan and made a David Lynch fangame recently (it's on Itch) so I absolutely am going to have to check the Rusty Lake series out, thanks for the rec!
I agree about near-realism in games. There's something very appealing with artstyles and narratives that have a sort of fractured verisimilitude. It's almost like real life, but there's a hit of something awry, without being blatantly fantastical.
