Commander Keen: Vorticons

You play the role of Billy Blaze, eight year-old kid genius who builds an interstellar ship when not working at home on his college fast-track degree. Among other household objects, Billy uses his Nintendo joystick for flight control and his mom`s vacuum cleaner (heavily modified) for his ship`s ion propulsion system (with pile height adjustment). At the hint of galactic trouble, Billy dons his brother`s football helmet and becomes "Commander Keen"--defender of EARTH! Ever on the side of justice, Keen dispenses justice with an iron hand."Marooned on Mars" is episode one of the Commander Keen trilogy. Only part one is available via shareware distribution, the other two episodes ("The Earth Explodes" and "Keen Must Die!") may only be purchased from Apogee.
