Save Mary is a game that was developed for the Atari 2600 but was never released. It does appear as one of the selectable games on the Atari Flashback 2 system.
Mary is in the bottom of a canyon that's slowly filling up with water. You must rescue her by dropping blocks down into the canyon to form a structure high enough for Mary to climb to higher ground so you can carry her out with your crane. Be careful not to drop any blocks on Mary, because that can make you lose one of your lives.
