I loved Silo S1.

You can save wherever you want but ya, it is a game you would want to play consistently. Like taking a month break would be tough. But that’s how most 1 player story games are, to me at least.

I also recommend Baldurs Gate 3 and Elden Ring. Baldurs Gate has one more big patch in the next month or two so I would wait until then to play it. I’m kind of waiting for that patch to drop to start another run through. Protip: pick the Dark Urge backstory.
