Although you might not assume so from the title, this is a maze
game in which you have not only a three-level maze to contend
with but also a set of monsters. As usual in these games there is a
map for you to consult showing where you are and what is there
with you.
I must remark how useless the instructions are though. There is very
little real explanation of the task before you, and the aids you
have to navigate by, which include sonar and direction indicators.
There is even a mistake about which key to press in one case.
The screen is changed very quickly, so the waiting is kept to a
minimum. The directional cursor keys are detected very slowly however
and have to be held down. Perhaps the joystick is more responsive in
use.
The range of opponents isn't restricted to monsters, there are also
indestructible balls, bombs to defuse, lifts to negotiate and keys
to find. All told, an interesting implementation of an old idea which
is badly let down by the skimpy instruction sheet.
