Clockwiser Amiga

On each of Clockwiser's levels (100 on Amiga/Amiga CD32 and 110 on DOS), you are presented with a level layout, and a target layout, with the aim being to transform the former to match the target. The levels consist of a collection of cogs, which can be rotated either clockwise or anti-clockwise to achieve this goal. There are lots of special blocks to help out, including bombs, diamond-producers and anti-gravity blocks. Each level has its own time limit, ranging from seconds to minutes - this doesn't start until you make your first move, and you can look around the level at your leisure before making a stab at it. Each level has its own password, which makes progression a little easier.
