Skies is available today, I hope you will enjoy it !
Unfortunately, some of you have problems during installation :( Let me tell you I'm deeply sorry about that.
Know that you can try to download it through the Desura website instead of the Desura application, it's been proved that it works way better !
We are, of course, going to look into the issue, and hopefully it will get corrected in the next days ! Sorry about the inconvenience !
