.Sh DESCRIPTION
|
||
|
|
In
|
||
|
|
.Nm ,
|
||
|
|
you are a little worm, your body is the "o"'s on the screen
|
||
|
|
and your head is the "@".
|
||
|
|
You move with the hjkl keys and the arrow keys (as in the game snake).
|
||
|
|
If you don't press any keys, you continue in the direction you last moved.
|
||
|
|
The upper case HJKL keys move you as if you had pressed
|
||
|
|
several (9 for HL and 5 for JK) of the corresponding lower case key
|
||
|
|
(unless you run into a digit, then it stops).
|
||
|
|
.Pp
|
||
|
|
On the screen you will see a digit, if your worm eats the digit is will
|
||
|
|
grow longer, the actual amount longer depends on which digit it was
|
||
|
|
that you ate.
|
||
|
|
The object of the game is to see how long you can make the worm grow.
|
||
|
|
.Pp
|
||
|
|
The game ends when the worm runs into either the sides of the screen,
|
||
|
|
or itself.
|
||
|
|
The current score (how much the worm has grown) is kept in
|
||
|
|
the upper right corner of the screen.
|
||
|
|
.Pp
|
||
|
|
The optional argument, if present, is the initial length of the worm.
