This is a super cozy story. I also like that it switches up it's various mechanics at certain points to keep things being different. I would have like to be told when things were entering free roam instead of just getting stuck throwing myself against the phosphor spirit for half an hour, as well as being told what Job Points were (sure, they made sense when I found learn skill, but I didn't know to look for it until I was well past stuck). You do a bunch of good things to mitigate this, but players don't tend to go looking for them if they think they have a path forward.
It would also be nice to have pregnancy be a little more prominent, like, it's visually there and the spirits go in the belly, but it's more just an occasional story mention than having any real effect on what's happening (even considering the ending).
But this was just a really well done, creative and as I said, cozy experience.
