Hints
Jump onto the Escalators, You'll save some time.
Don't get stuck on the roof, there's no way down.
Don't jump over the beach balls when they bounce high up.
Always duck under airplanes.
The Elevators
Ignore these unless they're convenient. Most of the time spent waiting for one is better used running toward an escalator. Also, the Krook will change direction if you get onto his level in an elevator.
