After the nuclear holocaust, according to Micro Power, we will all revert to cavemen playing life-or-death games of Rubble Trouble - or Pengy, as it was known before the bomb dropped.
Apart from us cavemen, the only other creatures to have survived are Krackats, mutated turtle-like things "whose only diet is that of human flesh". A little salty, I would have thought, and not really giving all the vitamins that a mutated turtle might need, but if that's what they like, who am I to argue?
As in Pengy, the screen display consists of a number of blocks forming a maze. You have to slide the blocks around in order to squash your enemies. The interesting thing about these blocks is that they bounce - if you don't hit a Krackat they'll rebound and crush you.
There are three mazes for players to choose from: regular, hayfield and vanishing. A lot of practice on the first is needed before you will competent to tackle the others.
Rubble Trouble has chunky, colourful graphics and the animation of the small but powerful caveman is pretty good.
The best feature of this program though, is the sound. The game begins with a skirling bagpipe-style tune and each time you lose a life, there is a morbid little organ piece.
Rock-throwing might not be a pursuit to everybody's taste, but in this program it proves to be enjoyable and not too taxing on the muscles.
This is a very good version of an arcade original with some interesting original touches of its own.
