According to the cassette insert, this is an "Adventure Game, set in
a hidden gorge in the Mountain of the Golden Lion, where you must
destroy monsters".
You see a number of diamonds - "monster places", connected by
lines - "bridges", through which you move to the finish by cursor.
Reaching a diamond produces a monster - which turns out to be a
test of some kind: memorise letters displayed for eight seconds
or a whole word shown for a microsecond; mental arithmetic, and
a number of mini-games.
An interesting idea, but not the adventure game you were led to
expect and the times allowed for completion are utterly unrealistic.
The games each use different movement keys and are very
unresponsive, while objects you must avoid fill the screen so
rapidly that even the Fastest Fingers in the West could never make it.
In one test, you are supposed to complete the fourth number in a
squence and my maths expert could find no logical sequence at all,
nor was there any apparent difference between the three levels of
difficulty.
Definitely a "try before you buy", and perhaps the publishers
should be a little less misleading in their insert description.
