The Floating Door

IMPORTANT: When you meet the postman, please click E

You're a spy, which is hard. You also have a meeting at Spy HQ in literally 20 minutes, and you recently lost your keycard to an alligator attack. Luckily, there's a network of floating doors that will get you to the floor you need to be at in roughly 20 minutes. Unluckily, since the doors are floating, you need to build up to them. Explore rooms, solve puzzles, and build a staircase up to the floating door to get to your meeting on time!
