After 2 years of development, here it is released and available in the Downloads section.
Back then many people were unable to download the ZIP version (more than 1.000 people if I recall correctly).
However I submitted a ticket to Gamefront directly, and they fixed the problem (thanks!), so now all downloads should be working.
So to whoever was still waiting for a working ZIP version from Gamefront, you can download it now :)
Sorry for the inconvenience.
