Main idea

I feel that the theme for this pyweek22 is sufficiently imprecise to allow me to use an idea that I wanted to put in a game for a long time. I would like to code my own procedural terrain generator, and I think that "you can't let him in here" is quite a nice theme for an exploration game. There is a guy. There is a big, big, big map. You have to explore the map in order to find the guy. Because you can't let him in here.
I coded the whole night to obtain a satisfactory result, but I'm happy now. I will add screeshots tomorrow if I'm less tired than now. I hope that I can finish to finish to implement the kernel of my game by tomorrow night, so that I can spend the rest of the week in appending content, debugging, gui-coding, and tuning graphics.
