Wow...
it's the most addicting game I've played all day. Once you get the first 200 points, it changes character shape, speed and color. I've gotten' a little over 500 points (character#3). The arrow controls work great; All I could see improving on would be adding some audio, and some kind of graphic background or something. It also needs to save scores.
Very creative and well thought idea. Great job.......vp
