text: The main focus of LittleBigPlanet is the level editor, located on My Moon. The editor incorporates a large number of editing tools and objects, accessible from the Popit, to create levels from a low to a high degree of complexity. There is a collection of interactive tutorials that are required to be completed in order to use their respective tools. To facilitate the creation process and to accommodate any mistakes made, the editor features a manipulatable time system, whereby the player may "rewind" the editor, which acts as an undo feature, or pause the editor, which temporarily halts objects that run under the physics engine, such as gravity acting on falling or rolling objects. The player may create new objects by starting with many basic shapes, such as circles, stars and squares, and "drawing" a shape into the level using one of the many materials. Objects may be glued to each other or to the level. More mechanical features are also available, such as connecting objects together with string, using bolts to spin objects, or using various kinds of triggers. Rocket motors can be attached to objects to propel them across a level. After creating custom objects, the player may save their creation to a library for later use, and share their object by placing it inside a prize bubble in their level, so that other players who play the level can collect it and may use it in their own levels.
