Haven't played Obra Dinn yet (it's on my list of games to play together with my wife), but anything by its developer Lucas Pope is a masterpiece. Papers Please, while it infuriated me at times (apparently I suck at following rules and spotting differences) was just amazing. Available on mobile and PC.
Also if you have the delightful "Playdate" game console, his game Mars After Midnight is charming and not stressful.
I would love to play that! I love the idea of the Playdate but with a Switch that is gathering dust, I don't think I can convince my wife to let me get another handheld :')
