Pencil Whipped, released in 2001, might be the most well known of the 3D Game Creation System games and one of the only ones to utilize a later version of the engine. The game won developer Lonnie Flickinger (aka Chiselbrain Software) a chance at the $15,000 Seumas McNally Grand Prize and awards for technical excellence, game design, visual art, and audio. Based on a strange dream Flickinger had, the game became known for its unique black and white pencil drawn world and for its wider novelty value, being described by Wired.com as "like being trapped inside a very disturbed child's drawing." In 2006 work was done towards a sequel on using The Game Creators tools, and more recently work has been done on an iPhone remake called "Escape From Big Ass Castle," which was originally released in 2012 for ios6 on the iPhone, but has been taken off of the market to be redone for the io7.
