Gamasutra recently posted an Interview with the FTL devs about the games design.
“We started with a very vague idea for a concept and used that as a guiding light for the entire project,” said Davis. “By having one singular focus we were able to abandon everything else that didn’t fit in line with that vision.”

Yay for team FTL! I had the opportunity to Help Kickstart this project, and it was really interesting to see it grow into the game that it is today. I'm glad that you enjoying your time with it, jdodson!
Yeah I am too. Its a great game to play when I don't feel like anything particular and just want to play something. And since I have it installed on all my computers Win, Macbook and Linux workstation, I can play it whenever.
