Awesome sauceome game!
It's weird, though. I've got a solo game of exactly this genre that I was just gonna bug test and release today before I thought I'd better prepare for exams instead :P And I'm pretty sure it uses some of the same audio guys too.
Anyway, the graphics were the dictionary definition of immensity. Whoever thought up the colour schemes is a bloody genius. The coding was incredible too. The only real problem was the lag, but I'm blaming Macromedia for that rather than you guys.
Here's to AS3!
