Drawn to Life preview at 1-up.

"We have an extensive preview of the gameplay from a Nintendo press event two months ago (read it here), but that deals heavily with the platforming and object-editing side of things. At E3, we got to check out a bit of the story elements. Since we last saw the game, Drawn to Life's cartridge size has actually been upgraded (which is more expensive for the developers); you can now save up to 150 images, and the gameplay has been extended (about 15 hours to play through, not including all side quests)."
