About Castle of Secrets
Castle of Secrets is a story-driven psychological mystery adventure in which you play as Miss Susan, a young woman caught in the ancient curse of the Tranton family. After her father, Mr. Grinn, dies under mysterious circumstances, Susan’s grieving mother, Miss Agatha, remarries the wealthy and intelligent Mr. Austin. The family’s fragile peace gives way to whispers of curses and sins, and Susan sets out on a perilous journey into the realm of the dead to discover who was responsible for the massacre of her family.
Explore the castle
You explore 3D environments in a point-and-click format, examining, collecting and manipulating objects with an interactive scene camera. You can search hidden corners of the castle, analyze what you find and combine items to uncover secrets and progress.
Solve the mystery
Puzzles are woven into the narrative, and their solutions directly affect the course of the story. You encounter more than 30 unpredictable characters: some may help Susan, while others may deceive her, and each has their own agenda. Your choices shape Susan’s fate, with multiple possible endings.
A hand-drawn world
The game combines 3D environments with hand-drawn 2D characters. Its original art gives the castle and its inhabitants a distinctive atmospheric style.
