Sylviana: Ai Ippai no Boukensha/Walkthrough

Progress
You begin the game near the north west corner of the Light World, at the home of your mother, where she lays i bed stricken with a mysterious illness. Your goal is to locate Dr. Doppler, find out what he needs to secure the medicine that will cure your mother, and then collect those items. This journey will take you across the light world, from the west side to the east side and ultimately to the mirror dungeon in the north east corner of the Light World. Inside this dungeon is a mirror which transports you to the mirror image of your home world, known as the Demon World.

Specifically, you must journey to three different towns, and explore a number of caves, towers, and castles. When visiting towns, you can restore your health and buy equipment for your adventure. When investigating the various dungeons, you must search for treasure that can aid you, including life-meter extending hearts and stronger equipment. At the same time, you must be careful to avoid trapped chests which can harm or even kill Sylviana. Eight of the dungeon locations contain a boss lair, where you must do battle against a demon who possesses a piece of Dr. Doppler's items. Your adventure will not be complete until you obtain all eight of Dr. Doppler's items, and defeat the demon Gengar in the island castle in the south east corner of the Light World.

Sylviana does not collect experience points or rise in levels. Her strength is determined solely by her equipment and the number of hearts that you manage to collect. Money is a strong component of this progress, so it may become necessary to fight monsters for an extended period of time just to get enough money for the next upgrade to your equipment.
