From the NintendoLife review:

While the campaign is varied and fairly lengthy, clocking in at over ten hours, Revelations is packed with extras and additional game modes. In the campaign alone you start with two difficulty settings, while completion of ‘normal’ will unlock the ‘hell’ mode, a New Game+ that allows you to retain weapons and items from the first playthrough. The standard setting is challenging in its own right, with boss fights a sticking point in the balancing of difficulty. We progressed well, with few deaths, until the first major boss encounter: in these difficult sections the otherwise solid controls can perhaps be a problem, with the dodge move – Up and B together with good timing – being particularly awkward.
