Just a quick note that the upload of the latest version of the DRM free Mac version created an issue that prevented it from being successfully unzipped. The folks at Humble Bundle have resolved the problem and the DRM free Mac version is now ready for download. We apologize for the inconvenience, and appreciate your patience on this.
