Castle of Secrets - about the game
Young Miss Susan confronts the Tranton family curse, venturing into ghostly realms to expose the truth behind her family's massacre. This storyline-driven psychological mystery adventure unfolds in haunting 3D castle environments paired with hand-drawn 2D characters. Players point-and-click to explore, collect items, solve narrative puzzles, and interact with over 30 unpredictable residents whose agendas shape alliances and deceptions. Choices drive a branching story toward multiple endings, where combining objects and logical challenges reveal buried secrets. Puzzle solutions alter the plot's direction in this indie adventure. Fans of point-and-click exploration and cerebral mysteries will uncover every hidden truth through careful analysis.

The ancient Tranton family curse has forced young Miss Susan to embark on a perilous journey—one that will take her deep into the realm of the dead. Along the way, she will encounter ghostly inhabitants, forge unexpected alliances, face formidable enemies, and, most importantly, uncover the answer to the most haunting question of all: Who is truly responsible for the massacre of her entire family?

One day, in the grand halls of the Tranton family castle, a loving couple welcomed a daughter into the world—her name was Miss Susan.

Her father, Mr. Grinn was a man of remarkable charm and influence, deeply adored by his wife and daughter. But tragedy struck when he met a mysterious and untimely death.

Grief consumed Susan’s mother, Miss Agatha, who found herself lost in sorrow, wandering the castle like a shadow, unable to bear the weight of her loss. Those around her, hoping to bring her solace, arranged for her to remarry. Her new husband, Mr. Austin was a rich and intelligent gentleman. This union brought a small sense of order back into the family.

Yet this fragile peace was nothing more than an illusion.

Like a black cat prowling in the night, misfortune slinked through the halls, leaving whispers of curses and sins in its wake…
