Instructions
Load "Little Big Planet" and select "MyMoon" from the main menu. Load an existing level or start a new one.
Press "Square" to open the Popit menu, and select the "Goodie Bag" option.
Select a building material to use and choose the square shape to place it in the world with.
Press and hold the "X" button to place the material in the level. Increase the size of the tool with the right-analog stick. You will need to create a large block of material to function as the walls of your maze.
Press "Triangle" to remove sections of the building material to form the maze. Start at the bottom of the material block to make the entrance. Cut multiple pathways in the material to create an intricate maze.
Cut an exit pathway opposite the entrance. You should now have a very basic maze in your level. Save your work and exit creation mode to test it.
