Mr. Do! game
Mr. Do! (ミスタードゥ Misutā Du) is an arcade game created in 1982.
The object of Mr. Do! is to score as many points as possible by digging tunnels through the ground and collecting cherries. The title character, Mr. Do is constantly chased by red monsters called creeps, and the player loses a life if Mr. Do is caught by one. The game is over when the last life is lost.
Cherries are distributed throughout the level in groups of eight. 500 bonus points are awarded if Mr. Do collects eight cherries in a row without stopping. A level is complete when all cherries are removed, all creeps are destroyed, "EXTRA" is spelled, or a diamond is found.
Mr. Do can defeat creeps by hitting them with his bouncing "power ball" or by dropping large apples on them. While the power ball is bouncing toward a creep, Mr. Do is defenseless. If the ball bounces into an area where there are no creeps to hit (such as behind a fallen apple), Mr. Do cannot use it again until he has retrieved it. When the power ball hits a creep, it then reforms in Mr. Do's hands after a delay that increases with each use.
Mr. Do or the creeps can push an apple off the edge of a vertical tunnel and crush one or more creeps. If an apple falls more than its own height, it breaks and disappears. Mr. Do can also be crushed by a falling apple causing a loss of life.
Occasionally, the creeps transform briefly into more powerful multicolored monsters that can tunnel through the ground. If one of these digs through a cherry, it leaves fewer cherries (and fewer points) for Mr. Do to collect. When it digs under an apple, it often crushes itself, other creeps, and/or Mr. Do.
