Mr. Do!/Walkthrough

Stage arrangements
Mr. Do! consists of ten different dirt arrangements or stages. Each of these ten different stage arrangements has 4 different predetermined apple positions, for a total possibility of 40 different stages. As you go from scene 1 to scene 10, you will be presented with a new stage until scene 11, when the cycle of stages will repeat itself. After any stage that ends in a 3, 6, and 9, you are provided with a status screen, indicating your progress through the game, and how each stage was completed. After any stage that ends with a 0, you are given a more comprehensive status screen which indicates your current play averages. A cherry indicates that the stage was completed by collecting every cherry. A monster indicates that the stage was completed by destroying every monster. A letter indicates that the stage was completed by spelling out EXTRA and earning a free life, and a diamond indicates that the stage was completed by collecting a diamond from a fallen apple.

Strategy
Killing all of the monsters is the best way to complete a scene, unless you can get a diamond or the last letter in EXTRA. Use the apples to get maximum points, then get the bonus prize when you have one or two monsters left. Save the power ball as a last chance weapon. Since the apples can be dropped one level safely, Mr. Do can set up little traps for the monsters. Dig straight up the column next to an apple, drop the apple one level and hide behind it. Push the apple so it hands out over the open pathway. Wait for the monsters to come up underneath the apple. When one of them turns into a striped creature, push the apple on top of them and dig to another apple. One the higher scenes, don't wait for the monsters. The striped ones will dig under the apple and kill themselves.

Earning extra lives
Earning extra lives is the only way to stay in the game, so it's important to know how to hunt down letters with as little danger to yourself as possible. Know which letters you need (these are the white, non-highlighted letters), and how far away you are from your next multiple of 5000 points. If you earn your next 5000 point multiple while clearing a stage, the letter will come out at the beginning of the next stage. E and A come out less frequently than the other three letters. Letter will chase you when you're not holding a power ball, and run away from you when you are. Don't give up your power ball to shoot a letter if it means being defenseless against a nearby crowd of monsters. However, if the letter you're about to shoot is the last one, you may safely disregard the monsters since the stage will end as soon as you kill the letter. It is difficult to kill a letter with an apple, since they will usually turn to face the apple and eat it, but it is possible.
