In a magical kingdom, a princess awakes after sleeping for one hundred years inside a castle filled with puzzles. Confused, she receives a message from the Fairy Queen explaining that all the answers are to be found on the castle grounds. She must explore the place to uncover all mysteries and discover her destiny.
Awakening: The Dreamless Castle is an adventure title with hidden object challenges and mini-games. Most of the time, the objective is to explore the many rooms of the castle, solving all the puzzles found on the locations to open new passages and gain access to other places. There are hidden object challenges in some scenes where the goal is to find and click on all the items listed at the bottom, on areas filled with assorted paraphernalia scattered throughout the scenery. Some of the collected objects are added to the inventory slots at the bottom interface, from where they can be dragged and dropped on logical places to perform an action or complete a task. The hint button is a fairy at the bottom-right corner, that shows the position of one of the required items, but takes some time to recharge after use.
Some of the puzzles are self-contained, taking place on a separate screen where a mechanism of some sort has to be manipulated to repeat musical sequences in a Simon game with a music box, finish a variation of mahjongg, reassemble broken statuettes by placing the pieces in their silhouettes and complete other similar challenges. Other puzzles require some information available elsewhere to be solved. The clues are automatically annotated in the journal at the bottom-left corner.
