FROSTBITE (ATARI 2600)

You are an Eskimo who wants to build an igloo to live in during the cold season. To do this, you must jump from ice block to ice block, while avoiding wildlife like birds and crabs. Upon contact with any of them, they will push you off the block and into the deadly water. Once you've built your igloo, you must enter it to advance to the next level. Remember, you have to build it before the temperature drops to 0°. You have four lives.
