You may be familiar with games guiding caterpillars around the Spectrum screen gobbling bugs (a useful attribute for a micro game) and avoiding deadly mushrooms. If you are, then you already know this game. The caterpillar is constantly on the move. You may turn him (or her?) anticlockwise with the 1 key and clockwise with the 0 key. These are well-chosen controls but they're all you get. Your only other choice is the speed of the game, a range between 1 and 9. The faster speeds are almost impossible. At 9 the caterpillar seems to race off the screen before you have any chance to press a key though a little practice makes it almost manageable.

I think this game will pall with extensive play - it lacks variety and visual attraction, though the programming and the display are perfectly competent. There is also a tactical drawback in play. If you keep pressing the same key, thus travelling in a perpetual square, sooner or later the bug wanders into your clutches. This is a boring way to play but reasonably effective and indicates the failure to consider how players will really play and what they actually want from a game.
