.Sh NAME
.Nm worm
.Nd play the growing worm game
.Sh SYNOPSIS
.Nm worm
.Op Ar size
.Sh DESCRIPTION
In
.Nm worm ,
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 (as in the game
.Xr snake 6 ) .
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 of the corresponding lower case key (9 for HL and 5 for JK, or
until you run into a digit, whichever comes first).
.Pp
On the screen you will see a digit.
If your worm eats the digit it will grow longer by that number of "o"'s.
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
.Pq 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.
