In LittleBigPlanet, players control small characters (nicknamed either "Sackboy" or "Sackgirl", owing to their material and appearance), each of which can jump, move, and grab objects. Players can use their abilities to shape and develop the highly manipulatable environment to build custom spaces either individually, collaboratively, and/or competitively. Levels focus on co-operative, physics-based gameplay, and players can use mechanisms such as cogs and blocks to build anything from small level parts to large, complex worlds. The game will also allow opportunities for players to acquire new skills and tools.
A major focus of LittleBigPlanet will be on the global community features through the PlayStation Network for players to interact and share their "patches" - levels and other modifications - as well as online play.
Players can navigate their way through the world by jumping, pushing, grabbing, running to overcome numerous puzzles provided by the game's robust physics engine. Players will also face physics-based enemies ranging from the small such as burning logs, to big "bosses" built around one of six AI "brains" available in the player's toolset. In addition, harmful objects can be placed in the game, such as pits of fire and being "squished" or flattened by an object that cause the player to restart that section of the level; players pop and roll out of restart points nearby.
A scoring system is also in place, in the form of a time trial with a start and end gate and players collecting world items such as sponge. Scoring is based on both time and execution of the level.
