I've improved the hit detection slightly, made it harder by increasing the speed, gave more starting health, added a help menu, and tweaked a line or two here and there. Eventually, I hope to have difficulty settings (Easy, Normal, Hard, etc.) that would determine the speed and amount of starting health. I'll add more music, too, and make it user selectable. All that will come eventually, but please let me know what you think as I keep upgrading and resubmitting this. I'm open to all comments, good or bad.
Updated: Just a quick thanks to all the people who kept this alive and gave me the encouragement to work on it more.
