I haven't beat all of them but Dig 1 and 2 are definitely way shorter than I wanted (I'd pay full price for an endless mode DLC lol).
Except Hades, Supergiant games aren't super long. Bastion and Transistor are decent, and Pyre might be a little longer but is pretty unique.
I'm interpreting your list of games as semi-casual with a strong unique flavor. The messenger is a little harder than the others but still not super long.
