Kuru Kuru Kururin is an unusual game that is a mix of racing/puzzle genres. The player controls a slowly spinning stick called the Helirin, and must maneuver it through a series of mazes. The player controls the direction and speed of movement but not the Helirin's constant rotation.
In this fast-paced TAS, Ryuto chooses to ignore damage penalties in exchange for blazing fast realtime completion and creative methods of getting around the Helirin's forced rotation to squeeze into even the tiniest of gaps.
There is also a run of the sequel, Kururin Paradise.
