SOME MINOR SPOILERS AHEAD!
Not sure if it's a feature, or a bug, but I think Mind decreasing as fast as hunger is increasing is pretty annoying. It could be a bug, since I'm almost sure it only started decreasing once I went into one basement (makes sense why mind would decrease in the basement), but didn't stop decreasing after that. But if it's not a bug, then at least items restoring mind should be as common as ones restoring hunger.
Another thing, not sure if I wasn't screwed by RNG, but throughout whole Demo I couldn't find a single item that I could draw with, when I saw plenty of places that required something to draw with, and it sucked to not be able to do that. It would be nice if you'd add Quill and Ink. or a Pen (since it's more modern times than F&H) at mayor's house library, would make sense to have items like that there.
Aside from those things, I think that Termina is a huge improvement over original thanks to better save system (good to have beds, and it seems like Books Of Enlightment aren't RNG-based anymore), guns being interesting way to conquer some challanges (it felt so awesome to kill Chaugnar with rifle without even entering combat!), and better rewards for actually killing enemies (at least now you can trade their heads for Soul Stones). I look forward to seeing full release!
