That's a cool callout - when I was making this game, that "surface level" rest felt like just another obligation, in order to enable some other obligation. I think the whole game was about obligation, now that I'm revisiting it.
I try to see resting primarily as self-care, but mostly during exam periods at uni, I (also) had the "okay, now I need to sleep so I can study more effectively after" approach, so I see how sleep can be an obligation/instrument.
