aw man, I knew I'd forget something.

around line 86 there's a while loop with a ground hit test.
inside that while loop add

ySpeed = 0;

and she won't fall full tilt immediately when walking off an edge. I thought something felt off with that.

you can change the maximum fall rate with lines 26 - 28
if(ySpeed > 10){
ySpeed = 10;
}
just raise the 10's for a faster top fall speed.
