That last part is exactly the issue. I never walked to the kitchen. Why would I have any need to if I am unaware of there being a hunger system and the tutorial thus far only tells me about working at my office and training the slave? You buy the slave, the tutorial says take her home. Then, you talk to your servant who says she can help train the slave but never has a command to do so (and whenever the slave is being trained there is a different NPC doing it in her room and the one we are discussing now is wandering the house at the same time). That same NPC also teaches you about the scribe job and then that is it, at that point, you have a quest to buy five high quality meat and a red wine for her, and then the bottom of the screen says to train and sell your slave. So, the typical player is going to focus on the training of the slave and the acquisition of the meat and wine as nothing says to go explore the house for more tutorials or anything about the food system.
Also, if I'm supposed to get paid 6 or 7 rather than 3 each time I do the scribe job, I wasn't getting it. I got at most 5 and only twice. The rest of the times it was giving me 3. Be it a glitch or whatever, IDK, but I stand by my statement. I'd take a screenshot, but as I said I uninstalled already. Best of luck on the game, though. Sincerely. The concept seems really good and I hope it goes well for you.
