Commander Keen — About this game
This handheld adventure has its own stages and story rather than simply presenting the old DOS episodes. Choose an appropriate difficulty, study each platform before committing to a jump and use the password option to return to saved progress. Finding the crystals links the separate worlds to Keen’s larger rescue mission.
