Mario starts at the bottom of the level near the ladder he needs to climb while watching out for the roaming Sniper. The elevator on the right does not move, so Mario has to pull the lever to the right to activate the elevator. Mario must then go over to the elevator and ride it up to the key. After collecting it, Mario must then go to the left elevator that goes down to get back down, then use the Spring to bring himself and the key up to the lever. Mario must drop the key to switch the lever to the left, but must do so quickly before the key returns to its original location. The lever changes the elevator next to it to go up instead of down. Mario must ride the elevator up to the top while still avoiding the Sniper, then jump over the hole and climb a series of "stairs" leading to the door, ending the level.
