Pitfall II: Lost Caverns is a platforming video game originally released for the Atari 2600 in 1984. The sequel to the popular Pitfall!, it opens up the world into a free-roaming adventure instead of progressing on a linear path.
This run is different from the any% TAS (http://tasvideos.org/3237M.html) in that it does everything necessary to achieve the maximum score. This means avoiding falling down pits (which decreases your score by 100 each time) and following a much longer route in order to obtain all items.
Alyosha improves the previous run (http://tasvideos.org/2673M.html) by 9.11 seconds, thanks to a new trick and better optimisation. Please read the author's comments (http://tasvideos.org/5253S.html) for more details.
