I think the handheld version may have a level editor, but PC doesn't seem to have one. There's a petition thread on the Steam discussions area asking for it (http://steamcommunity.com/app/218680/discussions/0/882966056655823147/).
Aw maaaan. Maybe somebody could mod it in? I guess with both things there'd theoretically never be a need for another Scribblenauts.
