An alien astronaut has arrived on a planet of mazes. Earlier, the reconnaissance expedition discovered very valuable materials here - round crystals. They took samples and found that small luminous pebbles can serve as a powerful source of energy. The hero in Alien Step must find and collect all the stones. Help him, the mazes are full of traps that are better not to step on. Move the gray blocks to clear your way or close the holes through which it is impossible to jump. Think over the way so that the hero remains alive and with prey.
