Tip for anyone who plays: the NPC's when they hit the walls they go in a random direction, including right towards you. So be careful with any NPC's who hit a wall.
Another one: Read ahead. Look abit far from where you are and try to predict where the NPC's are going to go and where is the safe spot. check where you are still tho, dont just stand there like an idiot.
Final Tip: always go to the most emptiest area, no matter where it is, i the middle, side, just make sure your in a safe zone.
Good luck you can do this.
( oh and if your wondering how long the hallway is its only like 2 or 3 turns, i dont remember but yeah )
