Hexuma: Das Auge des Kal

Hexuma – Das Auge des Kal is interactive fiction with graphics and a point-
and-click interface.

This German-only game is the last of three text adventures created by the
Weltenschmiede team, the other two being Das Stundenglas and Die
Kathedrale. Hexuma sends you into an old, supposedly haunted mansion, which
turns out to be a gateway to six different periods in Earth ‘s history. Travel
from the age of dinosaurs to the distant future and bring back six crystal
shards to battle the sinister god Kal.

Otherwise a conventional text adventure in its design and functionality,
Hexuma is aiming for the versatility record: the game knows six different
ways to enter a command. You can simply type it in. You can click on objects
in the graphic window to trigger the most probable action. You can piece your
sentence together in an icon menu. You can consult a list of pre-fabricated
commands tailored to the situation. You can click on any word in the text
screen to copy it in the command bar. And, strangest of all, you can enter
your command letter by letter with the mouse on a display of a keyboard. Talk
about German diligence.

There are a few puzzle dead-ends, so you might consider saving frequently.
