Now the thing is out - we ended up in 4th place - yay! :)
You can now download the XNA Creators Club version (to run on your Xbox360 if you have a CC license) or the video capture made by the Assembly compo crew (note that the capture it is slightly off-sync).
We hope you enjoy it! A final (and hopefully a Win32-build) will come as soon as we feel like it. :) There are a lot of things we want to finish, to make the demo more like we really wanted (but couldn't, because of time restraints).
Off to sleep now!
