DEMOLITION ---------- We do not understand how this game can be so addictive. The basic concept could scarcely be more simple. It is a Breakout-type game in which you are required to blast away an advancing wall before it crushes you. There are tactics to be employed, like hitting foundation stones and bringing down a series of bricks above them, and attacking the next wall in the series through the gaps in its predecessor; the multi-coloured bricks are very pretty; the finger work could not be easier, but why do we become so wrapped up in the thing? Perhaps we are just claustrophobics. The game was submitted by D Valentine of Mansfield, Nottinghamshire. (16K Spectrum).
