Use the lift, go in and out and go up and down using the stairs! Press <- and -> keys at the same time to safety break the lift. Can you find the key and the keycard? (It's on a different floor every time). To scan the keycard, drag it onto the reader, and then click the reader. When the light on the reader turns green, the cancelled floors are unlocked. To surf the lift, click on the right landing door, only if you have the key.
