Zartacla is the 135th level in Chip's Challenge Level Pack 2. The obvious backwards "Alcatraz" might suggest a hard puzzle, and in fact, most of the blocks around the level are mined. The hint states that paths one square wide lead to death, two spaces wide lead to the different sections of the level, and that the one path three spaces wide is the path to the exit. Being a Tyrethali Ansrath composition, it is thus far simpler than it appears.
