Uhm, there is really no such thing as a game making website. What you need is software, and seeing as all games on here have been developed on Flash CS3, there is no such thing as a free one. Flash costs 1500 dollars, but I think there is a beginners one for 700. Still, a lot of money. Sorry. You can make games with certain other tools and websites, but they usually don't save in the swf file, which you need to upload the game here.
