Level 2-3: Getting out of doors:
If you become stuck in the group of doors, go in the first door. You will see a square door and a circle door. Enter the square door, then the second door you see. Go to the second door you see in the next room, then the last door you see in the next room. If done correctly, you should be standing in a doorway with a row of yarn balls. Follow them to exit.
