Hmm... this seems like maybe taking things in an overly literal way. It sounds like clearing the tower was their threshold for a successful test - if they didn't get that far, it would be deemed a failure.
A phrase like "all I hope for" doesn't necessarily mean "the only thing I hope for" but instead usually means "the thing I hope for most (or above all)". If someone were to say, "all I want is a good night's rest", it doesn't mean they no longer want oxygen, for example. :)
