Nice to see a new update to the Kickstarter. I look forward to playing through the entire game using an Oculus Rift. Why don´t you put the game up on Steam Greenlight before you release it? That way your backers have some more time to vote for the game on there. If you put it up now, it might already get voted in by the time you are done.
Once the game is green lit, will your backers get Steam keys?
