Aww, bummer. I ran out of time so I didn't actually test the windows build at all. I can't get it to work on my windows 7 machine. I'm afraid to run it on windows you'd have to download the source from the github link. I don't think I can remove the windows binary at this point so I'll just add a big warning in my description. Thanks for trying!
Edit: hmm, you can just download the source as a .zip and import it using the godot binary provided in the windows build. It seems to work there. I have no idea why it doesn't work in the binary (probably something to do with using an alpha version :] ).
