Wrong parameters :MOV edx, maze
Undefined var:edx

What I have tried:

section .data
    maze db '#########', 10
         db '#     # #', 10
         db '# ### # #', 10
         db '# #   # #', 10
         db '# # ### #', 10
         db '#     # #', 10
         db '#########', 10
         db 'Time left: $'
    mazeWidth equ 9
    mazeHeight equ 7
    playerX db 1
    playerY db 1
    timer dw 30 ; 30 seconds timer

section .bss
    oldTimer dw 1 resb

section .text
    global _start

_start:
    ; Initialize the game
    call drawMaze
    call startTimer

gameLoop:
    ; Check for keyboard input
    call getInput
    ; Update the game state
    call updateGame
    ; Check if the timer has run out
    call checkTimer
    ; Loop back to the start of the game loop
    jmp gameLoop

drawMaze:
    ; Draw the maze to the screen
    mov edx, maze
    call printString
    ret

printString:
    ; Print a null-terminated string pointed to by EDX
    mov eax, 4
    mov ebx, 1
    int 0x80
    ret

getInput:
    ; Get keyboard input and update player position
    ; This is a placeholder for actual input handling
    ; You would need to implement keyboard interrupt handling
    ret

updateGame:
    ; Update the game state, move the player, etc.
    ; This is a placeholder for actual game logic
    ret

checkTimer:
    ; Check if the timer has run out
    mov ax, [timer]
    cmp ax, 0
    je gameOver
    ret

startTimer:
    ; Set up the timer interrupt
    ; This is a placeholder for actual timer setup
    ret

gameOver:
    ; End the game and display game over message
    mov edx, gameOverMsg
    call printString
    ; Exit the game
    mov eax, 1
    int 0x80

gameOverMsg db 'Game Over!', 10, '$'
