It's been a while since we've seen serious activity from Kloonigames' Crayon Physics games. From its debut as an experimental project in 2007 to the release of Crayon Physics Deluxe a few years later, the crayon-drawing physics/puzzle game went from being a neat-o toy to OMG WANT MORE. And now, not too long after its initial mobile release, the game has fully grown up and is ready for its HD iPad debut, sporting a few nice extras along with the visual upgrade.
