The Great Envelope Heist Escape Plan

Our team, "The Envelope Gang," has managed to get themselves taped to the wall in the most epic way possible. Now, we need your help to get us down.

Here's the plan:

1. Wait for the guards to leave for their coffee break.
2. Use the fire extinguisher to create a smokescreen.
3. Make a run for the door.
4. Climb down the wall using the sticky side.
