The story: You are Murphy, a bug-hunter inside the PC. Your job is to remove bugs from programs inside the computer. To do this, you must collect vital pieces of information, called infotrons. If you have enough, you can fix it, and continue to the next bug.
The game is divided into 111 levels, starting easy, and getting gradually more complicated, and harder to solve. Every level features one or more puzzles, which may require a good deal of thinking, and trying, to find the right solution.
The object of every level is to collect a fixed number of infotrons, and then get to the exit as fast as possible, without getting killed anywhere.
