I've been looking for this game again: Line Rider.
I found it over at Flashpedia: [linky] Go check it out.
I'm gonna dig in there a bit to see if I can find a couple of things I've been looking for. A good "Lode Runner" flash game and this cool game from a couple of years ago that followed this guy flying up into the sky...I can't really explain it but it was pretty cool.
