i assume :
Last updated in October 2001 (first issue i have with this)
now it's a zip, so i'm assuming you decompressed it using ark or some similar tool (this assumption stems from this being a game, so probably having graphics, so you're in some sort of GUI [don't mind this reasoning, this is part of my uni work ... it's affecting my sleep also :-P ])
14 more seconds ... shees lousy internet connection
Right, then read the README file and it will tell you to change the permissions to include executable. and away you go.
On that note, the game is buggy and i can't terminate it. meaning i will have to reset the X server ... How can people write software without a quit option??
