Help a guy out, won't you?  I'm trying to track down an old Commodore 64 game from my youth.  Players control a little blue camel-like guy as he moves back and forth on a seesaw.  Up above on a castle the evil overlord tosses multicolored bricks down on the seesaw.  The object of the game is to use the seesaw to propel bricks back up at the castle until eventually the camel-like guy can launch himself up in order to free his captured friends.  Does this sound familiar to anyone?  Can anyone tell me the name of this old game?  Better yet, can anyone tell me where I can find it today, either as the original version or a modern update?
