I am making good progress on the world editor for the little crane that could. I am creating a stand alone companion app for the game with which you can build your own levels. The levels are stored in iCloud, so that you can play them on any iOS device you own. You can also send your designs to friends via email. Here is a screen shot of the game menu that shows a user created level in the list.
The world editor and the game are both supporting the retina display of the new iPad. Man, oh man, that 2048x1536 resolution sure looks marvellous, and is ideally suited for level editing.
