This shows how lifts work. They go in a specific floor, they take you to another floor. Use the "FLOOR" to make the lift scroll up and down. Your current floor will be mentioned on the top right. If you take the Lift to the floor, you can enter the lift by clicking the lift and going in it use left and right arrow. You can then move the lift to another floor and escape after the lift stops. Press 'R' to go out of the lift.
