There's the link to 'games' on top. It takes you to see all sorts of categories (you propably knew that). Anyway, when I check for example the puzzle category, there are not all games that get submitted on NG. For example I was looking for mouse avoider games, and found only few. Im assuming only top games get into the categories? Where do the not-so-great-but-still-aproved games go then? How do I find some of them?
You can solve pretty much any problem you may have with AS3 by consulting the AS3 Language reference.
