I have a python script for a game and the problem is that after running the game, the blocks start falling, but the game over message is not popping up at proper times. Here is my script:

import pygame
import time
import random

pygame.init()

display_width = 800
display_height = 600

black = (0,0,0)
white = (255,255,255)
red = (255,0,0)

car_width = 45.2


gameDisplay = pygame.display.set_mode((display_width,display_height))
pygame.display.set_caption('pyrace')
clock = pygame.time.Clock()

carImg = pygame.image.load('theracer 1car.png')

def things_saved(count):
  font = pygame.font.SysFont(None, 25)
  text = font.render("Saved: "+str(count), True, black)
  gameDisplay.blit(text,(0,0))

def things(thingx, thingy, thingw, thingh, color):
    pygame.draw.rect(gameDisplay, color, [thingx, thingy, thingw, thingh])
  

def car(x,y):
    gameDisplay.blit(carImg,(x,y))

def text_objects(text, font):
  textSurface = font.render(text, True, black)
  return textSurface, textSurface.get_rect()

def message_display(text):
    largeText = pygame.font.Font('freesansbold.ttf', 115)
    TextSurf, TextRect = text_objects(text, largeText)
    TextRect.center = ((display_width/2), (display_height/2))
    gameDisplay.blit(TextSurf, TextRect)

    pygame.display.update()

    time.sleep(2)

    game_loop()

def crash():
  message_display('Game Over')
    
def game_loop():
  x = (display_width * 0.45)
  y = (display_height * 0.45)

  x_change = 0
 
  thing_startx = random.randrange(0, display_width)
  thing_starty = -300
  thing_speed = 7
  thing_width = 100
  thing_height = 100

  saved = 0

  gameExit = False

  while not gameExit:

    for event in pygame.event.get():
      if event.type == pygame.QUIT:
        pygame.quit()
        quit()

      if event.type == pygame.KEYDOWN:
        if event.key == pygame.K_LEFT:
          x_change = -5
        elif event.key == pygame.K_RIGHT:
          x_change = 5

      if event.type == pygame.KEYUP:
        if event.key == pygame.K_LEFT or event.key == pygame.K_RIGHT:
          x_change = 0
          
    x += x_change
    
    gameDisplay.fill(white)

    #things(thingx, thingy, thingw, thingh, color)
    things(thing_startx, thing_starty, thing_width, thing_height, black)
    thing_starty += thing_speed    
    car(x,y)
    things_saved(saved)

    if x > display_width - car_width or x < 0:
      crash()

    if thing_starty > display_height:
      thing_starty = 0 - thing_height
      thing_startx = random.randrange(0,display_width)
      saved += 1

    if y < thing_starty+thing_height:      

      if x > thing_startx and x < thing_startx + thing_width or x+car_width                   > thing_startx and x + car_width < thing_startx + thing_width:
        print('cross')
        crash()

    pygame.display.update()
    clock.tick(60)

game_loop()
pygame.quit()
quit()
