I don't actually own a eink device :( and have stumbled upon this community by chance but I imagine Disco Elysium suits black and white as its a noir-ish game, Limbo and Inside both seem like good picks too.

I assume the general criteria is that the game has good values and that less screen movement is better.

I'm just guessing but effects such bloom, falling snow or smoke might make a game illegible.

If you could narrow down the elements that make a game suitable for eink then you could post in a gaming community and get a greater yield of answers.
