Instructions For Use

Tooth Invaders

Starting The Game

1. Turn off your Vic-20 before inserting or removing any cartridges.

2. Insert the cartridge, with the label side up, into the expansion port on the back of the Vic-20. The expansion port is the opening farthest to the right when the keyboard is facing you.

3. Turn on the Vic-20. The opening Tooth Invaders title should appear. If the screen reamins blank after 5 seconds, turn the computer off, then on again. If this doesen't work, turn the computer off and remove the cartridge. Carefully re-insert the cartridge and try again.

4. Tooth Invaders is a one-player game. It is designed to be used with a joystick. Plug your joystick into the control port. Use the joystick to initially select your level, and later to control the movement of Plaqueman.

5. The title screen displays "Select Level." There are 9 basic skill levels to choose from. Important: Tooth Invaders is set to begin at a medium skill level (level 5.) Select a higher level by moving your joystick to the right, or for a lower level, move your joystick to the left. Following level 9, you're in the Super Skill level. Press the Trigger to begin.

Adjusting Screen Position

To center the picture use the (horizontal)CRSR and (vertical)CRSR keys. Each time you press the (horizontal)CRSR key, the picture will move to the right, and when the (vertical)CRSR key is pressed, the picture will move towards the bottom of your TV screen. Keep using these two keys until you are satisfied the picture is cenetered within your screen. (Note: Once the game has begun you can not change the screen colors.)

Eliminating Screen Flutter

On some TV sets with automatic fine tuning your screen may "flutter" up and down when using a computer or video game. To correct this, hold down the SHIFT key and hit the F7 key. (Note: Doing this with a standard TV set may cause the screen to flutter.)

Tooth Invaders (TM)

The object of the game is to elimiate all the plaque D.K., the Plaque Germ, has formed on all tooth surfaces, including in-between the teeth. This must be accomplished using the toothbrush (to clean tooth surfaces,) and dental floss (to clean the surfaces in-between teeth.) Special care must be taken to avoid colliding with D.K.... if you do, you will be elimiated.

The Tooth Invader: "D.K.", The Plaque Germ

D.K. forms plaque on all tooth surfaces, including in-between teeth. The object of the game is to clean away all the plaque D.K. has formed on all 8 teeth.

"Plaqueman"

Plaqueman uses a toothbrush and fluoride toothpaste to remove plaque from tooth surfaces. He also uses dental floss to remove the plaque that D.K. drops on surfaces in-between teeth.

Brush And Floss Power

Plaqueman uses a toothbrush to clean away the plaque on tooth surfaces.

The toothbrush, however, will not effectively clean surfces in-between the teeth. To clean these surfaces, dental floss is used. To switch from toothbrush to floss and vice versa, simply press the red trigger.

Danger -- D.K.!

While cleaning, Plaqueman must be careful to avoid colliding with D.K. If he does, Plaqueman will be elimiated and carried away by a balloon.

Decay Alert

Two warning signals will let you know when a tooth is decaying. They are:

1. You will hear a "beeping" sound; and

2. The tooth in danger will begin to blink a bright green color.

Practice Makes Perfect -- Try Again!

The game ends when all the Plaquemen are elimiated or when four teeth have decayed and disappeared.

Catch D.K. -- Earn Bonus Points!

When a tooth is totally clean, it will sparkle. Now you have 10 seconds to earn bonus points by catching and elimiating D.K. Listen for the music! When it stops, your chasing time is over and D.K. can now eliminate you once again.

The Fun Never Ends!

When four or more of the remaining teeth are all clean and blinking, you will move on to the next skill level.

The RESTORE key acts as an instant game reset. Hitting this key brings you immediately to the Tooth Invaders title page.
