Good stuff, added already into Knowledgebase.

Mike, would you mind mentioning the Flash version and/or AS version used in tutorials so people can know if they are able to use the source fla before downloading it?

I dont know if you plan to continue the tuts, but there is obviously need for next part, where enemies collide with hero, you lose a life and once you have no more lives the game ends. You would be surprised to see how many people have trouble ending the game.
