In the ZX Spectrum version, there's a hidden message found in the game's code from one of the game's developers, John Wood:


PROGRAM CODE 1987
HELLO THERE, HACKERS. YES, I KNOW THIS WASN'T VERY DIFFICULT TO GET INTO BUT I DON'T BELIEVE IN SPENDING TOO LONG ON PROTECTION (I.E. MORE THAN ABOUT 4 MINS, 33 SECS). PLEASE NOTE THE COPYRIGHT MESSAGE ABOVE WHICH I HAD TO PUT IN FOR LEGAL REASONS: IT MEANS YOU CAN'T LEGALLY USE ANY OF THIS STUFF. NOT THAT I THINK THAT WILL MAKE ANY DIFFERENCE, OF COURSE - NOR, INDEED, DO I PERSONALLY MIND AT ALL.

WELL, THAT'S
ABOUT ALL I CAN BE BOTHERED TO TYPE IN JUST NOW, SO BYE! (OH, IF YOU WANT TO WRITE, YOU CAN GET IN CONTACT WITH ME, JOHN WOOD, C/O ODE, 78 CHURCH WAY, IFFLEY, OXFORD OX4 4EF; BUT BE WARNED I'M VERY BAD AT REPLYING TO LETTERS.)

P.S. A RECOMMENDATION: READ ALAN MOORE'S 'THE WATCHMEN' - IT'S BRILL!
