You don't necessarily have to know where to go to finish it, and I don't think that necessarily makes it hard either. You can beat the whole game as a level 1, however enemies get harder, but they stay the same way if you can figure out your strategy. Unforgiving, dark souls doesn't hold your hand and tell you every little bit. It lets you decide on what you want to do with an epic, expansive, yet linear, game. Dark souls is a masterpiece and some people don't understand that because they are babied too much and then get plopped in into an unforgiving world where you are the one who decides how you play it, what you do, and how you overcome the challenges placed upon you all while being enriched with story that is all around you, in item descriptions and inscriptions around the world that tell such a rich and deep story that is a lot of speculation as well.
