+# Program Documentation
+
+## Overview
+This program is a simple game implemented in MicroPython for the Raspberry Pi Pico with a Pico-LCD-1.14 display. The game involves controlling a character to avoid obstacles and score points. The program includes a splash screen, game over screen, and a main game loop.
+
+## Framebuffer
+The program use framebuffer to draw the game graphics. The framebuffer is a 2D array that represents the pixels on the display. The program uses the `framebuf` module to create and manipulate the framebuffer. The framebuffer is then copied to the display using the `blit` method.
+
+## Multithreading
+
+The program uses multithreading to handle the game logic and the display updates separately. The `threading` module is used to create and manage the threads. The game logic is run in a separate thread from the display updates to ensure smooth gameplay and responsive controls.
+
+
+## Game Logic
+
+The game logic is implemented in the `game_loop` function. This function runs in a separate thread and handles the following tasks:
+- Updating the game state based on user input and game rules
+- Generating new obstacles and updating their positions
+- Checking for collisions between the character and obstacles
+- Updating the score based on the player's performance
+- Sending the updated game state to the display thread for rendering
