Everything on Planet Nubium – from the weather to the economy to the transport systems to a myriad of gadgets – is controlled by a supercomputer, which is malfunctioning. Reboot the supercomputer by negotiating levels and collecting objects to make the password that resets the machine. A rocket will propel your character upwards and gravity will pull you back down again. Avoid the guardians and keep an eye on the limited fuel! After collecting all the objects, return to the spaceship to advance to the next level.
