This is an excellently presented game, with a lot more to it than meets the eye.
Before you start, the program offers you the choice of sound or silence, and the option to define your own control keys. There are nine skill levels and you have five lives.
The screen is divided into squares, and you control a little man as he hops from one square to the next. Each time he steps on a square, it is removed from the grid. Mr. Livewire (as he is called) cannot cross the gaps he leaves behind him in his travels.
Time-bombs, flags, and skull-and-crossbones appear on various squares. Mr. Livewire must pick up the flags, avoid the skulls, and defuse the timebombs before they explode. You must avoid the giant boot which will cost you a life if it catches you.
Once you have dealt with five timebombs you move on to the next level. Here you face an extra boot, and the time-bombs explode quicker. You can be pursued by up to four boots at once.
Strategy enters the game when you find yourself cut off by blank squares. You can then scroll the row you are on to bring a filled square next to you, but rows can only be scrolled until a flag or skull reaches the edge of the screen.
Although fairly simple in concept, Gridtrap is a challenging game that requires a good deal of strategic thinking in order to get high scores. If you do really well there's a competition for you to enter as well.
