Comet

This world was erroneously saved on a toolkit board instead of the actual starting board, School (board 3). Entering +DEBUG to circumvent the SECRET flag and re-saving it (or quitting the editor and playing) on that board is necessary to play this world.

I don't feel I have to worry about spoiling the plot, as you'll complete this game in 5 minutes anyway. Basically, all that happens in the game is that you leave school, find out about a comet, leave home with your family to flee the impending collision, jump out of your car, go up a mountain, and die from the comet. That's all that happens. I think there's supposed to be some deeper meaning to the plot, but I didn't pick up on it.
