It's not Dark Souls. It's neither harder nor easier, it's different. And that's great!
A few topics to consider:

• The combat is extremelly satisfying and fair;
• No bs monster placing (sup DS2);
• No janky hitboxes;
• There are no weapons or armor in the game (but there's still equipment to be found and crafted);
• The bosses are an absolute blast to fight;
• The story is not as convoluted as in the DS series, and I loved it.

All in all, a game with a good amount of challenges, exploration and good combat!
