You ride a unicycle and need to reach the goal triangles. The unicycle is powered only by the gravity. The twist is that the game takes place in a world with Nil geometry! You know those impossible staircases and waterfalls and triangles; Nil makes these possible. You gain speed simply by going in circles!
