I've checked it against the code in the video multiple times but am stuck

```import random

CELLS = [(0,0), (0,1), (0,2),
(1,0), (1,1), (1,2),
(2,0), (2,1), (2,2)]

def get_locations():
monster = random.choice(CELLS)
door = random.choice(CELLS)
start = random.choice(CELLS)

if monster == door or door == start or monster == start:
return get_locations()

return monster, door, start

def move_player(player, move):
x,y = player
if move == 'LEFT':
y -= 1
elif move == 'RIGHT':
y += 1
elif move == 'UP':
x += 1
elif move == 'DOWN':
x -= 1

return x,y

def get_moves(player):
moves = ['LEFT', 'RIGHT', 'UP', 'DOWN']
if player == 0:
moves.remove('LEFT')
if player == 2:
moves.remove('RIGHT')
if player == 0:
moves.remove('UP')
if player == 2:
moves.remove('DOWN')

return moves

print("Welcome to the dungeon!")
monster, door, player = get_locations()

while True:
moves = get_moves(player)

print("You are currently in room {}.".format(player))
print("You can move {}.".format(moves))
print("Enter QUIT to quit.")

move = input("> ")
move = move.upper()

if move == 'QUIT':
break

if move in moves:
player = move_player(player, move)
else:
print("***Walls are hard, quit running into them!***")
continue
if player == door:
print("You escaped!")
break
elif player == monster:
print("You were too young to die!")
break
``` MOD

Up is down and Down is up. The math is reversed on your UP and DOWN. Up should subtract 1 to get to lower numbered row. Down should add 1 to get to a higher numbered row:

```def move_player(player, move):
x, y = player
if move == 'LEFT':
y -= 1
elif move == 'RIGHT':
y += 1
elif move == 'UP':
x -= 1  # <-- changed to subtract 1
elif move == 'DOWN':
x += 1  # <-- changed to add 1

return x, y
```

After this change, it appears to work as intended.
