Perhaps you two could do an AMA style post? I mean, you already answer our questions on the forums but it would give you a chance to answer in more detail/in a different venue.
Some questions I would ask:
Both: How do you and Alex communicate/iterate with the creative process?
Alex: What is your rough time breakdown for idea work/coding/testing?
Both: Any favorite mods? (Might be too loaded.)
David: Are there any of the sprites you wish you could radically change? Not just details, but things like weapon placement, outline, etc.
Alex: What is your favorite drink?
David: If Alex told you to "Go nuts" and draw anything you wanted for inclusion in the game, what would it be? Share concept art plz.
Alex: Do you have any regrets choosing Java as the language for the game? Any particular frustrations/challenges? Things made easy?
I would also accept a blog post consisting of David's cats doing cute things. Perhaps with spaceships in the background.
