Fat Worm Blows a Sparky

Fat Worm is locked inside a Spectrum’s architecture, and is looking for a disk
drive, in order to produce a clone of himself, which he presumably will Write
Once and Read Many. He moves around the arrangement of chips, processors and
boards, with the aim of finding his way through. On the way he will encounter
bugs (of the insectoid type) which must be shot at, by ‘blowing a sparkie’ –
releasing a bolt of electrical energy. Mines and impact shots can both be
fired. Contact with these bugs causes them to jump on you, gradually slowing
your movement and sappoing your energy. You must collect spindles in order to
get rid of them.
