The Worst Astronaut

So at 2AM one night my girlfriend and I had an idea. I can't tell you exactly where it came from, but the seed of it was "Wouldn't it be hilarious to see an astronaut that was really really really bad at doing simple things? What if he forgot simple passwords, couldn't remember his home address, or locked himself out of his house?" That train of thought got us laughing, but it got funnier the more specific we got. "What if he locked himself out of the space-station?" Or even better: "What if he locked himself out of the space station because he forgot a 4-digit code to get back in?" For whatever reason that struck a cord with us and we laughed at the image of a piece of paper, with 4 numbers on it, floating away from a man desperately trying to move in zero-G. So we took that, and decided to make it into a game.
