An awesome 3D puzzle game, designed by Pete Cooke, some 30 or so years ago, remade for phone and tablet. The game play is based around controlling 3 spider robots, each with specific functions, walking them around levels filled with all sorts of other weird contraptions. The levels vary greatly in difficulty. Past the early few, there are many very challenging and satisfying ones.

The first 27 levels come free with the download; the remaining 90 can be bought as an in app purchase. A level editor is yet to be developed, but is planned.
