BUZZZ!
from ZX Computing, Dec'85/Jan'86

Derek Mearns has been a busy little B - he can be
seen buzzing around the Witney Honey pots.


In this game for the 16 K ZX Spectrum you must manoeuvre the fly around
the orchard to the fence on the other side. It differs from the normal
arcade games in that your movements are via an INPUT statement at the
beginning rather than by INKEY$ during play.

When run you will see a short title display followed by the difficulty
input. This determines how many apples you will get (eighteen times the
difficulty level). The screen display will then appear, with you at the
bottom and the fence at the top. You will then see the prompt "O.K"
indicating that you should now enter your commands using the cursor keys.
All the commands should be entered at the beginning. For example, if there
was a straight path to the other side except for one apple blocking your
way, then your input may be:

"77777777577877777777"

Notice that it is not necessary to finish at the fence, you may over-shoot
it. However, you may not under-shoot it. Should the maze be impossible
entering 0 will return you to the start.
