A very important egg risks drowning, and it's up to you to save the day. Your means of rescue will be a series of blocks that can be stacked (ala TETRIS), but you must act quickly-water will rise from the bottom of the screen as the game progresses, raising the difficulty level with each passing second. Not only that, but there are 30 different creatures who can take blocks away from your building! There are nine different modes of play to try, and as many as eight players can compete.
