So far in Lesson 1 we haven't done much except for preparing a welcoming text and asking the player for their name. Let's start setting up the game now.
The goblin will be hiding in our kitchen cupboards.

Add these two lines of code to the three you wrote in Lesson 1 (it's best to leave a blank line before them for clarity):
cupboard_door = "|_||_||_||_||_|"
