"Grid Hunter" is an addictive one screen game where you run in grid lines avoiding monsters and spiders. Being caught by one of the monsters you die. Having covered all four sides of the blocks you are given points and your bonus bar rises a little higher. A rounded block changes its color. You can see where you have walked, because every "step" made by you, changes its base color to green. Each level must be completed by collecting the fixed amount of blocks. You are given 3 lives but you can earn extra lives by reaching bonus milestones - 750 points and 2.000 points.
