Labyrinth3D
true 3D Labyrinths - generating, rendering, exploring, building
...In places where no sunlight, skylight or reflections of them can reach, lamps can be put. The geometry of the labyrinth is purposely held simple to allow for fast computation. The labyrinth is generated randomly, based on a single number, the "level number". There is also a level editor where one can place blocks and stairs by hand.
