The Jetsons in By George, in Trouble Again

You can choose to play as either George or Elroy in one-player mode, or play both characters with a friend in two-player hotseat mode. The gameplay is simple: use the arrow keys to avoid hostile robots; run, crawl, and jump your way to the next screen. You have three lives (called "days" in the game); losing all of them means restarting that level. There is also a strict time limit on each level in the form of energy counter: you will die when the countdown reaches zero. Fortunately, the game is neither difficult nor long enough to be frustrating, although the characters' movements are somewhat too "sticky," i.e. unresponsive to keystrokes.
