Not a whole lot to say, maybe that it's quite easy-going. gameplay-wise of course.
One thing I'll say though is that if you harvest all the organs of a "human", put the empty human in storage, and then harvest another human's organs and serve, the next day the empty human is still in the storage - you have to serve the selected human to get rid of it from the storage. And that, alongside not being able to scroll through the storage when you've got more than 3 humans, is annoying.
Tldr: Quality-of-life implementations are most welcome. Don't neglect them.
Also I find it funny how the humans are named characters. I even got REMILIA of all people in my playthrough, so guess what? I... couldn't get Remilia to literally eat her own heart out because when I bought Remilia there wasn't a heart :(. But it's still so funking funny I made Remilia eat her own lung and liver, here take a look:
