Hmm, I could swear I've seen one or two similar games to this entered into previous CGCs. Come to think of it, this game is almost identical to 24.364% of all the crap games ever made!
Luckily, this is a ZX81 game so the fact that it's a heaping pile of unoriginal repetitive tosh will go largely unnoticed as 97.376% of ZX81 games are identical to this and 98.265% of ZX81 users don't care.
