This document provides instructions for making a character move around a maze in Scratch without touching the walls. It outlines 14 steps to add code to the character sprite that uses "if" blocks to check if it is touching the wall color before moving in each direction, allowing it to navigate the maze successfully. The character is programmed to move 10 steps in the indicated direction for each arrow key press unless it would hit a wall, preventing it from passing through barriers.
