With some switch/case and some conditionals, I’ve got a cutie lil game I made for the codecademy class. Load it up if you like!

Edit note, for readability I altered some of the spacing and tabbing.

var user = prompt("You are wandering along Deck 7.  People don't use this one
as much as the others, and doesn't smell as much like gorba root, the principal
trade roughage of The Captaincy.  As you rest your bones to look out the 
viewport onto the planet whose gorba the crew of The Captaincy just acquired, 
your Eye Viewer switches to life:

\n\n'ALERT ---- ALERT ---- ALERT\n\n

SHUTTLES TO DISCHARGE IN THIRTY SECONDS'\n\n

Oh no!!  What do you do?\n
 - If you would like to contemplate a bit more, type 'think'.\n
 - If you would like to look around for something to entertain yourself 
   on the no doubt long, slow voyage to the next system with unknown 
   shuttlemates, type 'look'.\n
 - If you want to just get to da choppah, type 'shuttle'.").toLowerCase();
