Note: I added some more to this comment, see the <EDIT> sections.
Items names - If it is skill based then I can see that working, but it requires the characters to give more information. There should be an option to ask what the plant I'm looking for looks like. Using the soapwort as an example again, if she had just told me it has a white flower then that would have made it easier to find. A tutorial screen of some sort that explains that system, that item names will change to be more detailed as your skills improve, would also be good. Right now there's no way of knowing that.
Another example is Chamomile. On my first game when I needed Chamomile the first few I got actually said Chamomile Flower, but then all the rest just said White Flower. Since I had already found some that said Chamomile I didn't collect the white ones, I just got frustrated saying "This looks like the same thing! Why isn't it right?" I guess that may have been a bug, since if I successfully identified Chamomile once I should know it from then on. This happened with the Pennybun mushroom, too. When I collected it, and in my inventory it said the name, but then when I was at a stove to make Seaweed Soup it switched to just saying Brown Mushroom.
<EDIT> I had an idea, but it may be too much to ask for. Since the interface is a book, why not add a tab for something like an encyclopedia of plants (and maybe animals, too). Give each entry three things: A black and white sketch, the name, and a description of the plant. If you are told to find a plant you haven't seen then you get the name and description, but no picture until you find it. If you find one you haven't identified then you get the picture and description but no name. As you get more information from NPC and the world, and your skills improve, you start being able to fill in all the information. This would make it so you have a reference of what you are looking for, like the quest log says the name then if you need more info you could look it up in the other section. Just a thought.</EDIT>
Food - I did try to cook the wolf meat, but with the heat and duration options I couldn't find a combination that worked. I'll try more, but I feel like putting raw meat on a fire should be pretty simple. It should give a result of too rare, well cooked, or burnt, rather than the message about not being able to make anything with those ingredients. I stopped trying because I figured that message meant I was missing something
<EDIT> I figured it out now, high heat for 15 minutes gives normal quality. Still seems like for something as simple as a piece of meat it should work almost no matter what and just give terrible quality if it is under or over cooked. Or make it possible for food to burn if you set the time too long, making you loose the ingredients.</EDIT>
Personality - Backstory and character development, yes. From what I've played I know Yotra is a blacksmith, Alice is a farmer, Shaartan is an herbalist/alchemist, and Nami is... a mermaid. You don't really get a feel for who they are, just what they do. Pretty much any line of dialogue I've seen could be coming from any character and it wouldn't feel out of place, they aren't very unique. Some kind of character progression for romance would also be nice. I don't know if the dialogue matters that much yet, because I have only played trying to be nice, I'll try a new game choosing the rude options to see what happens. The closest thing to romance right now is earning their trust so that they will trade with you, but there's no feeling or flirtation.
Nudity - The problem is that it just happens. Like I said, the bathhouse makes sense, but all the rest are completely random. They say something like let's get food, or beer, or whatever, then boom, sex. I guess it goes back to the lack of romance too. I'd prefer something like a dating sim, or the relationship system in House Party, something that makes it feel more earned. If they invite me inside I want to know why, and what to expect. If that's not what you intended to make then I just had the wrong expectations, and that's fine. Not every game is for every person, so if you never intended to have that kind of romance then making it the way you want is what you should do, I'm sure other people will enjoy it as it is.
As for the quality - It seems like each scene is just an animation loop that will keep going until you end act from the menu, right? Ideally I'd prefer something more scripted, but I understand the limitations you are working under (you are just one person making this, right?) so I won't ask for something like a fully animated cut-scene, I know that's not reasonable. What I would like is if they had an ending. Either a set length or a player option to finish. It would just be more satisfying if the characters were, well, satisfied.
<EDIT> I tried a new character with different stat distribution and now I see that there is an ending, I just didn't wait long enough or have the perception to see the gauge. I also had enough charisma for the other bathhouse option, and I think it is broken. The camera was inside her head. It was all eyes and jaw, I felt like I was looking at some horror show.</EDIT>
<EDIT AGAIN> Auto-save. You need auto-save. Pretty much all modern games have some sort of auto-save or checkpoint system. I wasn't thinking about it and just lost a few hours of work when I died after not saving at all since starting the game. The fact that I died of drowning because "swimming" is just walking along the bottom of the water is also a problem. I don't know how hard it would be to impliment, but you really need the ability to hold space bar and go straight up in water. Either have something more like actual swimming or put the seaweed closer to the shore. Sorry for the rage edit.</EDIT>
