Ended up with 1 "Poor", several "Perfects" and mostly "Very Good" and an 8.7 overall score. Very addictive game and well put together. I may have overlooked, but is the source available? I probably should of just checked "View Source".
It's funny, I was thinking to myself, who could possibly play this game twice. I might misjudge as I'm not a big player myself, but I really through the interest of this was more techniques used (e.g. raphael.js) than the game itself. But I agree, nice UI, nice design and good idea.
