# 1. Define our Tag
# Think of this as writing the sticky note name in our code so Verse knows what we're looking for.

# This script will control the lights. It's like the brain of the puzzle.

# It's like the referee blowing the whistle to start the match.

    # This is the magic line. We ask the World to find all entities
    # that have our specific Tag.
