We had planned the first email to be a sort of short study guide for the concepts we're playing with in Chapter 1 of Starfighter, but then I had the traditional Rev 1 Weeks From Shipping freak-out and relitigated every concept from Chapter 1 and Patrick had to fly all the way to Chicago from Japan to help Erin talk me down and so now we've settled back into a solid plan for what the first ~20 levels look like and long story short update coming soon.
