1. You're walking down a hallway
2. Take a left!
3. You keep walking down the hallway
4. Take a right!
5. Then a left, then a right!
6. Then a left, then a right!
7. Then-then left!
8. Then-then-then right!
9. Then-then a BRICK WALL!
10. AAAGH!
11. You keep walking down the hallway
12. Take a left!
13. You keep walking down the hallway
14. Take a right!
15. Then a left, then a right!
16. Then a left, then a right!
17. Then-then left
18. Then-then-then right! Then-then-thеn right! (Hallway)
19. Then-then a PITFALL!
