For the Patreon release this reward has now ended and we won't be sending out anymore keys unless the backer was in the May distribution list.
We're now just waiting on the game getting approved by Valve before we move onto the public release, this will be the time that everyone else has the opportunity to purchase the game or redeem it for Kickstarter backers.
More information will be released when we have it, hopefully not too much longer. Thanks for your interest in Starnova.
