Minecraft Shrink Ray Map

Somebody has broken into your house! Wait... what is that gun? A shrink ray! Now you have to find the two halves of the key you have hidden and use them to open the door.

Rules:
Do not break or place things anything.

Do NOT move in the intro animation! When the map starts, stay still until the person shoots you with the shrink ray!

Bugs:
When the arrow to activate the shrink ray fires, it may miss the ray's trigger. Break the fence to get out and pick up the arrow, then go put the arrow back in the dispenser by the door. Then /gamemode 1 and fly above the bedrock circle, then /gamemode 0.

Extra Challenge:
Find the hidden chest.

Note: The MCEdit Schematic file is the world download! Not the actual MCEdit Schematic!

There will be a part 2. Be patient.
Edit: Sorry, there will not be a part 2. I have started a new map series, Aliens (NOT inspired by the movie!).
