Craftworld

From LittleBigPlanet Wiki

Craftworld was the name of the prototype of LittleBigPlanet, and featured a character named Yellowhead. The main feature was the physics engine and the ability to grab and pull stuff, both of which are quite similar to the versions of these features which ended up in LittleBigPlanet. The blue, purple, and yellow colours of the prototype would later be used when decorating Media Molecule's new offices in London.
