## Overview

Snake Eater is a single-file Pygame game. The main loop receives player input, updates snake movement and food/score state, checks collisions, then draws and refreshes the screen. The source is sampled directly; components below are logical responsibilities within that file, not separate modules.

Main entry points: [`Snake Game.py`](https://github.com/rajatdiptabiswas/snake-pygame/blob/master/Snake%20Game.py) (Main Loop)
