Remix This GPLv3/CC-BY-SA free game

Hi folks, thanks for welcoming me to the forum.
I have a free (GPLv3 for code, and CC-BY-SA for graphics/sound/music) puzzle combat game called XONG.
I have just announced a contest for people to download and remix XONG and share their remixes/redesigns.
The page is at http://dto.github.com/notebook/remix-this-game.html
There will be no winner, it's just a fun experiment.
What do people think?
