Reminds me of the "running on cars!" video that went over some of the teaching tricks in older video games. How it would show a new enemy or mechanic in a way that is safe, but then drop you in on it with changes such that they feel different. The final "climb" of Super Mario Brothers is a great example. Just taking out the lower parts of the tower adds to the tension, when it should have no impact.
