That's amazing! I would have loved something like this when I was growing up. If you can do that simple games would be no problem, and who doesn't dream of making their own games.

It's certainly possible to write very simple games. The tutorial I gave my daughter was a (very clunky) Space Invaders clone, and I'm going to have a go at something a little more advanced tonight - I've got to make sure she doesn't start overtaking me...
The one place it seems to fall down a little is managing multiple identical sprites - I looked at a rather more professional-looking Space Invaders that someone else had written and it looks like they needed a separate sprite with full code behind it for every single alien, although it looks like BYOB may address some of this.
