Most point and click adventures take about 6-10 hours in my experience. My favorites are the Monkey Island and Deponia games.

It’s the dream of just opening up your regular phone to have a small tablet, clashing with the reality that your phone will never be regular sized if you want it to be able to do this!

Maybe someday phones can be like 4mm thin, so doubling that for a foldable would be reasonable. But we are definitely not there yet.
