Hello World - 0.3

As the name implies, this is my first Pygame project. Made out of 100% concentrated boredom. When I made this game, I was more focused on learning the language than good style or how to distribute the program. The code is some really sloppy stuff, and the README isn't particularly helpful. I plan on using this program as my personal sandbox to learn new Pygame features, so if anyone sees any mistakes at this point, I'd appreciate advice/critique of any kind. It's an honor to be here! I really hope to learn a lot!

Version 0.3's here already! Normally I don't like to upload files so quickly, but I made a huge addition to the game. We can now load variable size maps (rather than everything being 10x10 tiles) and we've got a nice camera that follows the alien without being a pain. I also implemented Andy's idea and made it possible to destroy scientists (stick figures) by pushing them between a red block and the wall. Note that this update makes old map files obsolete. Very sorry about that. I hope you find the upgrades worth it!
