WOW. Just WOW. I'm not surprised this game is turning out to be somewhat controversial with players, but I'm so utterly glad that I took such a good experience out of it.
Combat is solid as hell, multiple sections of the game are devestatingly hard but satisfying, discovery feels extremely rewarding, and once you learn the true nature of the game it really becomes something special. If you really find it too hard, there are plenty of accessibility features, and if you find similar games too easy, this game has some really good challenge to it.
Just try it out. If you don't like it at first, stick with it for a while longer; you might find your opinion changing over time.
