Heh, sorry. Someone else asked for a list so I made a short one, figured I'll send it here as well :) They range in obscurity, but I'd not rate any of them as "mainstream".
In no particular order and in no way an exhaustive list:
Lies of P.
Baba Is You.
Ender Lilies/Magnolia.
Rain World.
Pillars of Eternity 1/2.
Return of the Obra Dinn.
What Remains of Edith Finch.
the "We Were Here" series.
1000xResist (played this one just a month ago, what a game).
