This game is an action-packed dungeon crawler RPG set in an old castle with a dark and foreboding atmosphere.

■Risking your life to explore
As the main character of this game, you are not some burly soldier or skilled sorcerer. As you battle monsters, even the small fry faced at the beginning can defeat you if you're not careful. To survive, you'll have to pay close attention to your surroundings and use a variety of tactics, sometimes hiding and sometimes delivering a surprise attack that leaves your enemies mortally wounded.

■Gaining strength through item alchemy
In this game, you must make all the essential equipment and healing items for your journey by yourself. As you explore the dungeon, combine the materials you find to transmute items. Craft powerful items and you'll be able to defeat enemies you couldn't handle before.

■Continually think of the best possible plan
You will be forced to make lots of decision to survive. Do you move forward or retreat? Fight or hide? Which items will you pick up, and which will you leave behind? Each choice you make will affect your survival rate.

■Dark fantasy world
Your father, the king and a great alchemist, was killed by a god from another world. You have returned to his abandoned castle to obliterate his murderer and get your revenge.

The castle interior is overrun with monsters, and there are also explorers of uncertain character searching for treasure inside.

Using the alchemy skills you learned from your father, will you be able to reach toe the top floor where the god who murdered him lies in wait...?
