Strategy

This page provides a comprehensive guide to Mr. Do! strategy. Arranging this page into a sensible format is not easy. After all, it's really just a series of tips that could appear in any order. I've decided to divide it into the same sections as in the Description page. There's also a Golden Rule which should be read first.

In the sections that follow, "scene 3" means scene 3 only; "scene *3" means scenes 3, 13, 23, etc.

Golden Rule

One simple rule dominates the game of Mr. Do! for all but the first few scenes. The rule is, always aim to move towards the top of the screen. Once there, move to a point immediately above an apple, and stay there. You will find that the diggers, in digging straight up towards you, dislodge the apple, which will fall on them and kill them. As soon as the apple starts falling, find another apple to move to and repeat the process.

Obviously, this technique will require some adaptation to the individual circumstances of each scene, but if you follow the basic idea, whilst preparing to be flexible, you should find your high score increasing. Sometimes, it seems just too simple; the diggers dig up towards the apple, commit mass suicide, and the scene is over within a few seconds.

The other main advantage of moving quickly to the top of the screen is for killing letters. You are in prime position for knocking off letters as soon as they appear.

This rule is amplified in some of the sections which follow.


Mr. Do!

Mr. Do! has six possible orientations. He can face left, right, up or down. When facing up or down, his feet can be pointing left or right. Since the ball is always thrown in the direction of the feet (see later in this section), this left-right orientation can be important. If you are facing up or down, and want to change your orientation, move slightly to the side you want your feet to point and then move back again. You will find your feet facing the opposite direction.

If Mr. Do! passes horizontally beneath an apple, the apple will wobble and fall, but only after Mr. Do! has passed. It is also possible to move downwards directly beneath an apple, then move out of the way just before the apple drops. You have time to move downwards two rows before the apple falls and crushes you. This can be a useful method of shaking off a red monster that is chasing you; the red monster is either crushed by the apple or is forced back.

It is worth studying the way Mr. Do! throws the ball. It is thrown from the shoulder, forwards and downwards (i.e. towards Mr. Do!'s feet). Once you are familiar with the way the ball travels you can throw the ball with a lot more accuracy, for example, you can fire past a junction of corridors and know which way the ball is going to go. This is very useful on scenes such as scene *9. In heading for the top of the scene, you have to cut through the horizontal corridor through the centre of the screen. After passing the horizontal corridor, if you turn-and-fire at the right point, the ball will move along the horizontal corridor in the right direction and quickly kill a red monster.

The following tips may help with regard to throwing the ball:


Red Monsters and Diggers

The behaviour of red monsters and diggers is complex and unpredictable. Only experience can teach you how they are likely to react in a given situation. A couple of facts can be observed here, however:

If a digger is digging straight towards you, and there is solid earth between you and the digger, a guaranteed way to kill it is to turn to face the digger and hold the fire button down. The ball with keep bouncing against the earth until the digger is almost upon you, and will then kill the digger. This technique is particularly useful for finishing off the last digger in a scene, when they can move very swiftly. Do not be tempted to move towards the digger whilst firing in this way. It almost always results in losing a life.

One situation which is difficult to handle at first is when you are in a horizontal corridor with a number of red monsters, with an apple separating you and them. They tend to dig upwards and around the apple, and will quickly catch you if you let them do this. There is a solution, however. Move downwards a fraction. This is enough to encourage the monsters to dig downwards. You can then push the apple, or move upwards, and the monsters will be squashed by the falling apple.

There are various technique you can use during the end game to kill a red monster that is following directly behind you. Firstly, avoid corridors. If moving along a corridor, the red monster will always catch you. If you are digging, the red monster will approach quickly, but not quite catch you. It will follow on your tail. At this point you require nerve and patience. If you change direction, it will catch you. If you continue in the same direction, however, it usually at some point changes into a digger and falls behind for a second or two, before catching you up again. This is your chance. If you have the ball in hand, you can quickly turn and shoot the red monster. If not, you can change direction. Aim to head under an apple or towards the nest. If you can pass under an apple, the red monster will probably dither and squash itself. If you can reach the nest and eat the food, the blue muncher phase starts and you're saved.

If a red monster is following you, but not quite "on your tail", you can escape by passing under an apple. There are two possibilities. If you pass straight under the apple and continue horizontally, the red monster will usually "dither" and get squashed. This is not guaranteed, however, especially in later scenes when you are one letter short of an extra life. The alternative possibility is to turn downwards directly beneath the apple, move one or two rows down, then turn off horizontally again before the apple falls. This will almost certainly kill the red monster. If it doesn't, it will delay the red monster, leaving you with time to escape. This can only go wrong if the red monster is already "on your tail", in which case it will catch you when you turn downwards.


Letters

However good you become at Mr. Do! you will always get killed occasionally. Sometimes so many red monsters turn into diggers that there is no escape. The only way of building a really big score, therefore, is to win plenty of extra lives.

Getting the Right Letter Out

You control when letters come out. The currently highlighted letter comes out when you eat the food or when you pass a multiple of 5,000 points.

Killing Letters


Muncher

Once the munchers are out, you have three ways to survive the immediate danger. The first way is to kill the letter. The second is to kill the three munchers. The third is to kill all remaining red monsters and diggers, thus ending the scene (you can also end the scene by eating all the cherries or finding a diamond, but these are extremely unlikely). The munchers move quickly, and you only have a very short time to decide which strategy to adopt.

Consider first whether you are in imminent danger. If the munchers are very close or if the screen is a tangle of corridors, you can quickly end the scene by shooting the remaining red monsters and diggers. This is easy if there is only one left, and often possible if there are two left.

If you're not going to end the scene in this way, you have three methods at your disposal. Which you choose will depend on whether you require the letter, whether it is the only letter you require, and which letter it is (E and A being more useful). The three methods are the Running Away method, the Looping method and the Isolation method.

Once you've finished the Blue Muncher phase, you're in the End Game. If there are more than two red monsters or diggers left, you'll find it very difficult to escape them. Therefore, if you have time during the Blue Muncher phase, try to kill off one or two red monsters or diggers.


Food

There are two reasons for eating the food. You score a large number of points (8,000 on scene 22 and above), and you trigger the release of a letter and the munchers. Either one of these is a good reason for taking the food. Together, they make it so advantageous that you should almost always eat the food if you have a chance.

Always keep half an eye on the highlighted letter, so that when you do eat the food, you don't get a letter you already have. E's and A's are highlighted less frequently, so try to take them in preference to X's, T's and R's.

There are two situations where eating the food is hazardous. Firstly, if a letter is already out and very close to the nest. If you eat the food, three munchers will materialise very close to you, and you may get killed. Secondly, if lot of earth has been eaten away, making a complicated maze of corridors, you'll find the munchers harder to kill, because they have a choice of routes towards you, and can cut corners as they approach. There's a particular danger of the dreaded double munchers, or even treble munchers. In either of these hazardous situations, one option is not to eat the food, and this can be the best option. However, 8,000 points for the food is very useful, and you may have a red monster on your tail which you can only shake off by eating the food. See Blue Muncher Phase for how to deal with these situations.


Apples

Apples have two uses: blocking monsters and squashing monsters.


Cherries

Eating cherries is usually a diversion from the main business of killing the various monsters and gaining extra lives. However, they can be important in various ways:


Diamonds

Your heart starts racing! Your palms start sweating! A cry goes up from all who are watching! It's a diamond! It's impossible to ignore! Every nerve bends towards the goal of reaching the diamond and winning the ultimate accolade!

Any Mr. Do! addict will recognise this scenario. Diamonds are in fact quite rare, and so feature low down on any list of tips. If you're really serious about getting a high score, my advice is to ignore all diamonds! They make you panic, and tempt you into foolish risks. I've lost more lives in trying to reach a diamond than I care to think about. However, they can be useful, and many players feel an obligation to do their utmost to reach all diamonds, so the following points might be useful.


Scenes

Early Scenes

I call scenes 1 to 10 the Early Scenes. Once you become reasonably adept at the game, these scenes should present no problems. Getting killed should be a rarity. Your objective in these scenes is to get as many extra lives as possible. The secondary objective is to amass as many points as possible. As a rule of thumb, aim at getting five extras in the first ten scenes, that is, one every two scenes. A points target is less easy to specify, but 140,000 after scene ten is good going. 120,000 is poor.

The main features of the early scenes are that diggers do not appear very often, and that everything moves relatively slowly. You have time to think and plan ahead.

Middle Scenes

Scenes 11 to 15 are the Middle Scenes. They are a sort of transitory phase between the Early Scenes and the Later Scenes.

The main feature of these scenes is their unpredictability. In scenes 1 to 10, you can be pretty certain that not many diggers will appear. From scene 16 onwards, you can be equally certain that the red monsters will transform very quickly. In scenes 11 to 15, however, you just can't tell what will happen. Sometimes a red monster will race along the corridor; sometimes it will turn into a digger and burrow straight towards you.

Later Scenes

Generally speaking, each scene can be divided up into a number of distinct phases: I call these the Opening, the Middle Game, Eating the Food, the Blue Muncher Phase and the End Game.

The Opening lasts from the beginning of the scene up to the point where you manage to move above the level of the nest. The Middle Game lasts up to the point where you Eat the Food, or manage to reduce the number of red monsters to one or two. The Blue Muncher Phase lasts from the moment you Eat the Food until you kill the letter or it disappears. The End Game lasts as long as the last two red monsters survive.

Later Scenes - Opening

Right from the start of each scene, you should aim to move above nest level. If you can do this, you have an excellent chance of surviving the scene. How you do this is largely a matter of experience. You'll need to develop a different strategy for each scene.

It is usually possible to shoot one or two red monsters whilst moving to the top of the screen. One some scenes, if you fire right at the beginning of the scene, before moving at all, you will always kill the first red monster. On other scenes, you can kill the first red monster by moving slightly and firing. Again, the precise strategy depends on the scene.

Generally speaking, the red monsters do not transform into diggers until you have had time to move to the top of the screen. If this happens, all well and good, the battle is half won. Sometimes, however, particularly if you are one letter short of an extra life, they turn into diggers right at the outset. If this happens, survival becomes a lot harder. As a general rule, if a digger blocks your way, you should immediately change direction and look for another route to the top of the screen.

The most common cause of death is diggers appearing right at the outset. Sometimes you get two diggers coming at you from different directions. In these situations there is a good chance you will die. If this happens, don't panic. If you're doing well, you'll have plenty of lives left and a chance to regain the life you lost. If you're going to die in this situation, it's important to take a few of the enemy with you. If you can kill two or three red monsters, there will only be five or six left when the scene restarts, and you'll have a much better chance of survival.

Later Scenes - Middle Game

Once you've passed the nest level, you're in the middle game. Once you've got the knack of this, it's easy. You just stand directly above an apple and wait for the diggers to dig up towards you and kill themselves. You must stand directly above the apple. A pixel or two either side is insufficient. The best way to do this is to point Mr. Do! so he's facing up or down. This ensures that he's directly aligned with the apple.

The middle game also provides opportunities for killing letters. Your ideal position is in the second row from the top. Don't break right through to the top row. As soon as a letter appears, you can stick your hand through the wall dividing the top row from the second row, and fire off the ball to kill the letter.

If you have time, you can prepare yourself for the next appearance of a letter. Point Mr. Do! upwards, just below the top row. If Mr. Do!'s feet are pointing in the wrong direction, adjust his position (see Mr. Do! section). However, be very careful doing this; this slight motion will divert diggers from their upward path, and they will avoid the falling apple. You can only adjust your position like this if the diggers are some way away.

Before taking a pot-shot at a letter that has just appeared, check there is no imminent danger from red monsters or diggers. The few seconds in which you'll be without a ball are a vulnerable time. One of the great skills of the game is knowing when it's safe to take a letter, and when to keep the ball.

Later Scenes - End Game

The End Game is defined as that part of each scene where there are only one or two red monsters or diggers left. At this point, the monsters become very fast and clever, and there are probably few apples left. You must concentrate on survival. Refer to the Mr. Do! and Red Monster sections for tips on finishing off the last red monsters.
