Here's a new video of the up and coming Flash 9 based Scarygirl game. You can see it at http://www.touchmypixel.com/
The games is running at 760x480 @ 30FPS, and is only about 2MB download per level. The final thing will have about 1 to 2 hours of play in it for a first timer.
Quite Mario-ish (you know, THAT Mario....oh don't start). Seriously though, this looks quite elaborate and imaginative, but I would have to play to see the intricacy and detail. Excellent demo.
