Feel free to ask questions!
UPDATE - Mac users: we forgot a single toggle for you! You might need to restart Steam to trigger the new build, but then you should download an actual game when you come back. (If you weren't a dev you couldn't access our Mac build.)
UPDATE 2 - WHITE SCREEN ISSUES: If you're getting this mysterious white screen problem, it would be a huge help if you could tell us some of your system specs (like OS, DirectX, ram, etc). We're not able to repro it and are trying to narrow down the causes.
