This is a tool-assisted speedrun. For more information, see http://tasvideos.org/220M.html Flashback is the sci-fi version of Prince of Persia. There is a lot of jumping, rolling and climbing to move around the levels. This movie uses a lot of bugs to get ahead faster. The most prominent one is probably walking through walls, which renders keys obsolete. Also, if you finish a level without having some important item, the game assumes you have it anyway. We recommend the author's comments of this run.
