I love the game. My only problem with it is that when Flash gets busy (lots of items on the screen), the controls get sticky. I've fallen off the side several times because I let go of a button while Flash was bogged down and it didn't register... so I kept going in that direction.

I'm on a dual 2ghz G5 with a gig of ram, running in Safari, in case you're curious.

As a side note, I'm an AS3 coder and though I love my current job that has nothing to do with games, it's stuff like this that makes me entertain thoughts of game development. I'm gonna go read the technical notes from your link now....
