Its not much, but I'm just excited about how easy it was to add these new features. Basically I just found a free sprite sheet at opengameart.org, added it to my game, and implemented the sprite animations. I also changed the game to support selection and moving of multiple units on the map. Feel free to check it out here:

EDIT: I should have mentioned that these features only took about 30-45 minutes of work total.
EDIT2: Many more features (and a new blog) since this post.
