The Manse on Soracca

The Manse on Soracca (also known as TMOS or simply 'Soracca ')is a video game developed for the Marduk Graphics Entertainment System by Aldebaran Interactive. It is a mystery-adventure game that puts the player in the role of Herbert Castaigne, a private investigator sent to search for a missing woman on the little-known island of Soracca.

Plot
"...One day, you receive a letter from a wealthy noblewoman. She pleads for your help in finding her daughter, Bridgette Camillia. The woman tells you that she sailed away for an uncharted islet known as 'Soracca' with a scholarly suitor, but it has been days since she was to return. Included was some information on how to find the island, as well as advance payment. With no reason to refuse, you sailed off toward the supposed islet.

Of course, arriving couldn't be so easy. You were caught in a nasty storm and thrown overboard. You was ashore a small islet... Could this be 'Soracca'? Who's to say? But you can't sit in the sand forever."

Gameplay
TMOS sees the player navigating The Manse and other adjoining areas, picking up items and avoiding the various monsters while solving the various puzzles scattered throughout. The player can investigate objects and scenery by pressing 'J', allowing them to collect clues and learn about the history of the manse. By pressing 'K', the player will use their equipped item, which can be viewed at the top of the screen.
