You need to define "mistakes" properly then, there are a lot of people here who would disagree with your opinion... do you think it would be fair to call ravioli a mistake because a person happens to prefer lasagna? different qualities have different value to different folk. This game might not be for you or you might be doing something wrong... either way defining it simply as a mistake is not an objective statement. I've never found the game too Grindy. Certainly not in comparison to some others I can think off.I’m not talking about bugs; I’m talking about the incredible grind which makes up most of Peasant’s Quest’s gameplay (and is especially egregious at the start of the game—the first five hours or so, by my count). I doubt it’ll change, because I doubt Tinkerer sees it as a problem in the first place.
Edit: Like DomWolf said, balancing "grind" is something you learn from trial and error via constructive feedback.
