イース — About this game
This is the Famicom version of ``Ys'', in which adventurer Adol crosses a storm to Esteria and travels in pursuit of monsters that suddenly appear and the mysteries of the island. Listen to the stories of people in towns and villages, prepare your equipment, and expand your exploration into forests, temples, and caves. Combat with enemies is not done by pressing buttons to swing a sword, but by moving and touching the opponent. It is important to devise ways of conflict, gain experience points, and grow while moving forward. Bought weapons and armor have no effect just by having them; they must be equipped on the item screen. You can stop and recover your life force in towns and fields, but there are some places where it doesn't recover in the same way, so it's important to prepare before going deeper. Memorize the clues you get from conversations, record your adventures, and gradually venture into dangerous areas.
