3. Take the soapwort root as an example. She just ask you to get it, without a single hint of where to look. When I finally found it the item I collected was "White Flower" and in my inventory it was just "Root". Even in the quest log it had some other name, it did not say soapwort root. A hint in the dialogue like "Near the village by water" or something, and some consistency in naming so that the name on the item I collect is actually the name of the item I am looking for. The other thing was the need to be able to ask the NPCs "What was it I needed?" If you accidently click through their dialogue too fast or just forget what it was there is no way to go back and find out.
5/6. The issue of money and hunger go hand in hand. At green hunger your capacity is 75%, yellow is 50%, and if it drops to orange it's only 25%. Ores are heavy, so if you are trying to mine for Yotra it's a race to get the money so you can get food so you can carry the ore to get money. Hides require combat, which means damage and bleeding. Tools and weapons also need repairs. The amount of money you need for food, medicine, and repairs is just too much compared to what you get for quests. Shaartan's herb quest, for example, takes 12 items (4 types, 3 of each) and pays only 0.15. The time it takes to gather those items burns through more hunger than the payment is worth. You get hungry while sleeping, too, and even if you aren't tired I found I had to sleep at night just to pass the time because it is too dark to do anything, the lantern doesn't give much light, and it costs too much to refill/repair the lantern. Honestly, I think an early game recipe that let's you turn wolf meat into a decent meal would go a long way in fixing this, since that is a food you can get without money.
7. Off the top of my head the only specifics I can think of are when Shaartan say something about her herb quest "isn't dusty", and a lot of the recipes mention letting the food digest. In both cases I'm not sure what you mean because those words don't make sense in that context. For the food digesting, does it mean over-cooking?
I started a new game after my comment to see how it was knowing more at the start. I did get further, and I also got to some of the nudity. The bathhouse makes sense, at least, but boy was I shocked when "I'm going to take a break and get a bite to eat, join me?" meant something else. I was expecting some kind of romance path through dialogue or something, not just random "let's take a break" scenes. I found this game from it being mentioned on the Steam forum for House Party, so maybe I just had the wrong expectations. As is, I think the nudity is the part of the game I like the least.
