The launch has been really wonderful and successful. To put it in perspective, we sold twice as many copies on Steam in ten hours than we sold via pre-order in the whole time after Kickstarter (and that's almost year and a half). The money we've made on Steam so far is already enough to ensure we have the budget we need to finish the game.
Thank you all wonderful and inspiring players for your enthusiasm, support and understanding! We are doing our best to resolve all the issues, especially with the game not starting on Win 8, this will be fixed shortly!
