Hack is a game resembling rogue (but much richer than the versions
of rogue I have had access to).
The game runs on all machines with sufficient address space:
$ ls -l /usr/games/HACK
-rws--x--x 1 play 159744 Nov 10 19:09 /usr/games/HACK
$ size /usr/games/HACK
text data bss dec hex
106496 34816 29264 170576 29a50
but if you are unfortunate enough to have a backward C compiler
(without structure assignments or bitfields or functions returning
structures or with only 6 significant chars to an identifier)
then you'll have to work to get this running.
I am happy with mail, but will be abroad the next four weeks.
Good Luck & Happy Hacking !
