Hi Scott,

I'm not an expert in Croquet, but what you explain leave me think that 
first of all, you need to learn a bit more how to use Squeak and his 
tools like the debugger. My suggestion is first to read a book about 
Squeak, for example you can download freely the "Squeak By Example" book 
here : http://www.squeakbyexample.org/
An another way to learn more how to use the development tools of Squeak 
is to find someone in your area who can you the tricks.
Lastly, you can also join the squeak-beginners mailing list to have 
answser to your questions. Look here : 
http://lists.squeakfoundation.org/mailman/listinfo/beginners

With the help of the tools (debugger, method finder and method 
implementors), you will easily see that the openInWorld method is not 
implemented in any of the subclasses of SimpleWorldDemo. Morph 
subclasses implement openInWorld, but SimpleWorldDemo is not a subclass 
of Morph ...

BTW, to open the tools you can use shortcut like ALT-B, to open the 
class browser.

Best regards,
