Interesting concept. I think it demonstrates program flow pretty well, however there are a few things that bother me a little about it.
1. The use of the goto statement. Granted, it's a legal operation, but I think it's an operation that needs to be taught with caution.
2. They don't assign the arithmetic operations to a variable. (i.e. x+2). They should have declared a second variable (maybe spaces, or movement) that determined how many spaces the player moved. As is, if you were trying to teach using this game, you'd have to explain that the value of x didn't change.
