The Hitchhiker's Guide to the Galaxy Game - 30th Anniversary Edition
A word of warning
The game will kill you frequently. It's a bit mean like that.
If in doubt, before you make a move, please save your game by typing "Save" then enter. You can then restore your game by typing "Restore" then enter. This should make it slightly less annoying getting killed all the time as you can go back to where you were before it happened.
You'll need to be signed in for this to work. You can sign in or register by clicking the BBCiD icon next to the BBC logo in the top navigation bar. Signing in will also allow you to tweet about your achievements, and for the game to tweet about your achievements too, if it feels like it.
