One trick is to edit a file /usr/include/GNUstep/Foundation.h on macosx and put 
#import <Cocoa/Cocoa.h> in it. Then again NSString is the way to go sometimes.

It was made for GNUStep hence the roguelike.

There is GS in this case on MacOS X, with some other framework library for iOS.

This is in development if I find the time for it.

Again, GNUStep is a UNIX/Linux system.

These are in ./Resources/. It uses the mouse not the keyboard :-)

Good points, Thanks for the comment. FYI, I am working on an ObjC game for 
iOS, called zoowy the wizard : http://code.google.com/p/zoowy/downloads/list

Here's a screenshot : http://zoowy.googlecode.com/files/zoowy-screenshot-1.png

It includes a XCode project file.

Enjoy and take care,
Fyndhorn Elder.
