Sega's Super Monkey Ball (2001) lets you take control of one of four monkeys trapped inside a transparent ball. You must complete each stage by tilting the game level to roll your monkey using the force of gravity and colliding with objects. There are over 100 unique levels ranging in difficulty from easy to near impossible.
In this TAS, the authors start at the Expert difficulty, where they proceed to tear through most of its 60 levels as well as the 10 Master levels, using warps where necessary and breaking most of the heavily optimized console world record times.
This TAS improves upon the previous publication (tasvideos.org/2567M.html) by nearly 16 in-game seconds, using many new route optimizations. More information can be found in the submission text (tasvideos.org/4859S.html).
