@Craigp I think the main counterexample I can think of is Spiritfarer.
It's a platformer - but it's a very easy one where you cannot die (it wouldn't do for the ferrymaster of the dead to die, would it?). It's also a resource management sim - but you have all the time you want. There is no way to lose the game, and you cannot truly get stuck. You care for the deceased spirits until they're ready to move on, and the only gameplay challenges are explicitly optional.
