PLATFORM JACK

by John Silvera

from ZX Computing Apr/May.1985



A three screen platform game from Minehead's jumpin' John Silvera!





Up and down, up and down, what a job! and I don't even get

danger money. The problem is that I have to work out the

order in which to make my rounds otherwise I lose my pay

bonus - or even my life.



All I can really say is "HELP!!!"



Although this program is written entirely in BASIC, it

incorporates some clever graphic routines, imaginative

sounds and a nice starting tune.



All instructions for play are shown when the program is run.

You will find that in places you cannot jump, but do not

worry, there is always a route for you to follow.



On each set there is only one main route so watch where you

are going.
