If you haven’t already tried them, I had a great time with Vampire Survivors and Loop Hero. Both give the player the ability to check out a little bit, though in different ways. Loop Hero is easier to walk away from than VS, but both games require the player to do little to nothing in order to engage in combat. Loop Hero is a little more involved while VS is a bit more arcade-y. Both very fun
Great pick. Obra Dinn is a masterpiece. If you end up enjoying Obra Dinn you’d probably also enjoy the Case of the Golden Idol and its recent sequel. Both scratch a very similar itch.
