Centrifugal Centinuum was a level made in Super Mario Flash 2 by JMuth561 (nowadays ZidaneZ), being known as the longest level ever made in Pouetpu-games, with a total of 208,000 x axis length. The main theme of the level was a night grassland design. Due to the length, a common problem with the level was that it sometimes froze the game while loading it.
The level was included on BRENDANT98's first edition guide as one of the recommended levels to check out.
The level was removed by ZidaneZ on december 2014.
