Simple game code

 Here is an example of a simple game code written in Python using the Pygame library:

python
import pygame

# Initialize pygame and create window
pygame.init()
screen = pygame.display.set_mode((400, 300))
pygame.display.set_caption("My Game")

# Game loop
running = True
while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False

    # Clear screen
    screen.fill((0, 0, 0))

    # Draw player
    player_image = pygame.Surface((50, 50))
    player_image.fill((255, 0, 0))
    screen.blit(player_image, (200, 150))

    # Update display
    pygame.display.flip()

# Quit game
pygame.quit()

This code creates a window with the size of (400, 300) and title "My Game". A while loop is used to keep the game running until the user quits the game. Inside the while loop, the code checks for a QUIT event, which is generated when the user closes the window or clicks the "X" button. The screen is filled with black color, a red square is drawn on the screen, and the display is updated. This simple game will display a red square on the screen and it will stay there until the user closes the window.

It's important to note that this code is just a skeleton and you will probably want to add more functionality to make it more engaging. Pygame library provides many more functionalities like sound, images, movement, handling inputs and etc.
