Apart from a freeze button and the
starter, there are only three controls on
this program - rotate left, rotate right
and fire - as you drive a mini-sub
through an unusual sea covered in
places by cuboid icebergs.
The sub has a constant forward
motion except at the screen edges, the
control being to change direction by 45
degrees on each key-press. Very tricky
to do, but a fascinating movement once
you get the hang of" it.
The action takes place in a
midground fashion under the icebergs
but over the background, so it is often
obscured and you have to steer by
guesswork.
You are attacked by - as far as I've
got - four different types of enemy
which are announced in a sententious
manner before each screen, first one at a
time, and then in various combinations.
A program like this can be very
annoying, because just when you think
you've got the feel of the control you
make a mistake - and don't get on to the
next screen.
In this annoyance lies its charm. It is
simple in concept, but very well
implemented.
The compulsion to play it just once
more before going to bed has caused
quite a lot of marital upset.
I must go now and have one last game
before I send the tape back to The Micro
User.
