Depending on what difficulty you're playing on this game can ranges between challenging to nail bitingly hard, but every longtime Ys fan knows that Nightmare is where the real party's at. This game is about bosses, and apart from a few sub par fights the bosses in this game are among the best and most satisfying you'll find in any game. This game is a prime example of picking up very simple, even barebones, gameplay mechanics and giving the player a high degree of freedom to use them and various ways and that, couples with varies and clever design, gives great variety and depth to what would otherwise be very simply gameplay. Stages are simple sure, but blaring music and high pace make this game a real adrenaline rush.
