Ys 4: Mask of the Sun
returns to the style of play used in Ys I and II. Adol is viewed from a top-down perspective, and he attacks enemies by running into them to cause damage. Adol gains experience from defeating enemies, and gaining experience serves to raise his strength, as in the previous games. A new Magic system is introduced as well, in which Adol can equip elemental swords to cast various types of attack spells.
