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.

Petri Purho of Kloonigames has a reputation for churning out experimental prototypes in a matter of days. In 2007 one of these prototypes was the sandbox-style puzzle game Crayon Physics. The premise was simple — use a "crayon" to draw shapes that immediately come alive and interact with each other, the ultimate goal being to collect a star somewhere on the screen. The experiment was a hit, and soon it was announced that a full-fledged version of the game was in the works: Crayon Physics Deluxe.
