From their Facebook (Bleeeeeh) post;
For those that got their Kickstarter keys and activated them. Well we did get the game up on time, it's just that we have to await Valve approval now. If you suddenly see the game go "downloading" then you'll know that Valve has set the game as live. smile emoticon
Thanks for your patience everyone, we wouldn't have even got this far without you.
Dunno about the site though, exceeded the data cap for the server they rented? Ddos attack? (already??) I dunno lol
