Journalist Nicole Rankvist receives a letter from Robert, her archaeologist
father, describing the discovery of the key for a powerful artifact called the
Crystal Portal. When he goes missing, Nicole must find the scattered pieces of
the key around the world.

The Mystery of the Crystal Portal is a hidden object that replaces the
traditional list of objects names with a different gameplay mechanic. The
player has to click on certain objects in the scenery that open a circle
around it with photographs of items that must be found and dragged to it.
After picking all the required stuff, some of these container objects
disappear to reveal a key item underneath them.

Some of the objects have to be collected in one screen to be used in another
place (for example, finding matches outside the house to light a fireplace
inside). At the end of each stage/location there’s a unique logic puzzle game
to be solved, involving some of the objects that the player picked up.
