Nil Rider: 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! What is Nil? Nil is a three-dimensional geometry. While in two-dimensional non-Euclidean geometries parallel lines converge (elliptic) or diverge (hyperbolic), in 3D they can also move in the third dimension. More precisely, every point in Nil has well-defined North, South, East, West, Up, and Down directions. However, the up/down direction works different than in the Euclidean geometry: when you make a loop which would return you to the same place in the Euclidean geometry, its counterpart in Nil changes your vertical coordinate by the value proportional to the signed area of the loop projected on the NESW plane.
