The object of Greed is to erase as much of the screen as possible by moving around in a grid of numbers. To move your cursor, simply use your arrow keys or the the 'hjklyubn' keys or your numeric keypad. Your location is signified by the @ symbol.
When you move in a direction, you erase N number of grid squares in that direction, N being the first number in that direction. Your score reflects the total number of squares eaten.
Greed will not let you make a move that would have placed you off the grid or over a previously eaten square. If no valid moves exist, your game ends.
Other Greed commands are 'Ctrl-L' to redraw the screen, 'p' to toggle the highlighting of the possible moves, and 'q' to quit.
The only command line option to Greed is '-s' to output the high score file.
The environment variable GREEDOPTS can override the default color set, which will be parsed as a string of the form:
where <cn> is a character decribing the color for digit n. The color letters are read as follows:
b = blue,
g = green,
c = cyan,
r = red,
m = magenta,
y = yellow,
w = white.
In addition, capitalizing a letter turns on the A_BOLD attribute for that letter.
If the string ends with a trailing :, letters following are taken as game options. At present, only 'p' (equivalent to an initial 'p' command) is defined.
