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. He must then grab it and go to the non-moving then go to the left elevator that goes down to get back down. Mario must use the Spring to get himself and the key up to the lever. Then he must put the key down and switch the lever to the left quickly before the key goes to its spawn place. The lever changes the elevator next to it to go up when it used to go down. Then he must ride the elevator up to the top while still avoiding the sniper, then he must jump over the hole so he doesn't have to start over and then go up some "Stairs" leading to the Door ending the level.
