They've just updated Voxatron, as well as adding Gish to the bundle.. you can get a Steam key. They also added some smaller, download-only games to the bundle.
And I still can't get Voxatron to respond at all. It loads up into the menu after the boar breaks through the logo, plays that chippy song... says Play, Editor, Options, or Exit.. and I can't get it to do anything after that. If anyone knows how to fix I'd really appreciate it.
