Day Two: Crawling

So on my first try today, Game Maker decided to not work. It wouldn't run my game. After reinstalling and hunting down my old license key, I finally got it up and running again, with not a whole lot of progress. I've got the turrets physically in the game, but they don't quite do anything yet. Again, no screenshots- they're coming, someday, I hope. I'm a bit worried, but I also know I'm saving the brunt of the work for the weekend, so the minor incremental progress isn't a major setback. You've gotta crawl before you can run, right?
