You go on a journey to a huge black hole lurking in the elliptical galaxy M87 on a UFO.
The road to the black hole has to travel through a complicated space like a maze.
The UFO moves in the direction with the right control lever, but to return, you can warp to that position by touching the warp point on the screen. Also, if the destination cannot be seen from a distance, you can check the destination by enlarging / reducing the screen.
