Space Station is a tabletop roleplaying tribute to a classic text-based computer game, but does not include the basic rules for the Parsely system. From the publisher's website:

> LOOK SPACE STATION

Parsely #4: Space Station is the fourth Parsely game from Memento Mori Theatricks. Now you can “GO UP” and “LOOK PANEL” with the best of them. You awake from cryonic suspension aboard a space station, apparently the only surviving crew member. You feel the station shake as an explosion impacts its shields, but will they hold? Parsely games are inspired by Ye Olde Text Parsers from days of yore, but substituting a live human for the computer parser. Parsely games are small, portable and fun for (almost) all occasions.

• Play them anywhere! On trips, in long lines, camping, at game cons…
  
• Play them with anyone! Young or old, expert or total n00b
  
• Play with a few friends or 100 random strangers at the same time
