Great stuff!

A few comments on the tutorial:

Probably worth mentioning up front that a game wouldn't normally be a  
document-based application (and say at the end what would be  
different to use a non-document application template).

Rather than editing the pbxproj file manually:
   Targets inspector -> rubyrocks -> Info.plist Entries -> Document  
Types -> Document Class

I couldn't see any instructions for binding GameView.game to the Game  
instance (File's Owner) in Interface Builder.

The instructions for adding the 'game' outlet aren't as detailed as  
the result of the instructions in Interface Builder.

You can just use [a,b,c,d] instead of OSX::NSRect.new(a,b,c,d)  
(similarly for NSPoint), unless you want to hang on to the object and  
use .x, .y etc.

The moveWithBounds_ and initWithPosition_ methods etc don't need a  
trailing underscore.

The model objects (Sprite and descendents) can be plain Ruby objects  
rather than NSObject descendents. This means you can use a normal  
ruby initialize method (instead of .alloc.initWith...).

Cheers,
