The scenery, though pseudo-randomly generated should be strangely familiar, specially to those still in their teen age. You can navigate using the keyboard arrow keys and the function keys. Your speed is a linear function of (n-1) where Fn is the last function key you have pressed, and you always move in the direction you are looking at. Be aware that you are probably some kind of a Creeper as is obvious from looking at the program, hence your movement is destructive to the environment. So after pressing F12 for warp speed, and moving around randomly, you might find yourself in a 3D maze of twisty little passages, from which there is only one Esc(ape) key. Note that in theory if you have a specialty keyboard with 32 function keys you may even press F31 to reach infinite improbability drive speed, though the author had never tested this feature.
