Helen knows little about who she is―or even where she is―and she's dying to find out more. Stranded on a floating island with a labyrinthine castle just begging to be explored, Helen lets her curiosity get the better of her. Fortunately for Helen, she's more than capable of taking care of herself.
Armed with a plethora of weapons she finds along the way on her journey, Helen must battle monsters, collect new equipment, and uncover the many secrets of her mysterious home.

Helen spends the game fighting on her own, and she wouldn't have it any other way. Using the game’s unique 1-on-1 combat system, Helen can collect weapons and toggle between them during battle as the situation dictates.
Take advantage of the passage of time and knowledge of your opponents to quickly swap in the right weapon for the job and finish off your foes before they have the chance to react.

Enhance weapons using experience points collected from defeated enemies, collect new weapons hidden deep inside the labyrinth, and put together the ultimate arsenal.
Equip and upgrade weapons of all shapes and sizes―from bows and shields, to broadswords and devastating magic spells. Learning when to use each weapon is the ultimate key to victory.

Death can come swiftly in the world of Helen's Mysterious Castle―but it's not the end of the adventure. Every time Helen perishes, she'll reawaken in the cabin with a piping hot Salisbury steak ready to be eaten. Gobbling up this delicious meal will grant a permanent increase to her lifeline, rendering otherwise-unbeatable foes just a little bit easier.FAQFAQ
