It looks like Celeste, Dead Cells, and Blasphemous are all three on Steam for Mac. Out of those three, I’d recommend Celeste probably. Unless you’re looking for a serious challenge and lots of dying, Blasphemous may be a good option there. Celeste can be hard too, but at least you don’t have to fight enemies. It’s mostly just climbing mountains and avoiding deadly objects.
