.Sh DESCRIPTION
|
||||
.Nm
|
||||
is a display-based game which must be played on a CRT terminal.
|
||||
The object of the game is to make as much money as possible without
|
||||
getting eaten by the snake. The
|
||||
.Fl l
|
||||
and
|
||||
.Fl w
|
||||
options allow you to specify the length and width of the field.
|
||||
By default the entire screen (except for the last column) is used.
|
||||
.Pp
|
||||
You are represented on the screen by an I.
|
||||
The snake is 6 squares long and is represented by S's.
|
||||
The money is $, and an exit is #.
|
||||
Your score is posted in the upper left hand corner.
|
||||
.Pp
|
||||
You can move around using the same conventions as
|
||||
.Xr vi 1 ,
|
||||
the
|
||||
.Ic h ,
|
||||
.Ic j ,
|
||||
.Ic k ,
|
||||
and
|
||||
.Ic l
|
||||
keys work, as do the arrow keys.
|
||||
Other possibilities include:
|
||||
.Bl -tag -width indent
|
||||
.It Ic sefc
|
||||
These keys are like hjkl but form a directed pad around the d key.
|
||||
.It Ic HJKL
|
||||
These keys move you all the way in the indicated direction to the
|
||||
same row or column as the money. This does
|
||||
.Em not
|
||||
let you jump away from the snake, but rather saves you from having
|
||||
to type a key repeatedly. The snake still gets all his turns.
|
||||
.It Ic SEFC
|
||||
Likewise for the upper case versions on the left.
|
||||
.It Ic ATPB
|
||||
These keys move you to the four edges of the screen.
|
||||
Their position on the keyboard is the mnemonic, e.g.
|
||||
P is at the far right of the keyboard.
|
||||
.It Ic x
|
||||
This lets you quit the game at any time.
|
||||
.It Ic p
|
||||
Points in a direction you might want to go.
|
||||
.It Ic w
|
||||
Space warp to get out of tight squeezes, at a price.
|
||||
.El
|
||||
.Pp
|
||||
To earn money, move to the same square the money is on.
|
||||
A new $ will appear when you earn the current one.
|
||||
As you get richer, the snake gets hungrier.
|
||||
To leave the game, move to the exit (#).
|
||||
.Pp
|
||||
A record is kept of the personal best score of each player.
|
||||
Scores are only counted if you leave at the exit,
|
||||
getting eaten by the snake is worth nothing.
|
||||
.Pp
|
||||
As in pinball, matching the last digit of your score to the number
|
||||
which appears after the game is worth a bonus.
|
||||

||||

.Sh BUGS
|
||||
When playing on a small screen,
|
||||
it's hard to tell when you hit the edge of the screen.
|
||||
.Pp
|
||||
The scoring function takes into account the size of the screen.
|
||||
A perfect function to do this equitably has not been devised.
