## Overview

This is a small Pygame learning project: the user runs the game, steers a moving rectangle with the arrow keys, and sees the playfield change color when it collides with one of four rectangles. The sampled implementation puts initialization, input, movement, collision checks, drawing, and shutdown in one loop in `main.py`; the README documents Pygame as a dependency. No separate snake-body, food, scoring, or growth behavior is present in the available source.

Main entry points: [`main.py`](https://github.com/mana2k/snake-clone/blob/main/main.py) (Game loop)

## Components

### Game loop

- [Player](https://github.com/mana2k/snake-clone/blob/main/main.py): `main.py`
- [Obstacles](https://github.com/mana2k/snake-clone/blob/main/main.py): `main.py`
- [Game loop](https://github.com/mana2k/snake-clone/blob/main/main.py): `main.py`
- [Playfield](https://github.com/mana2k/snake-clone/blob/main/main.py): `main.py`

### Pygame runtime

- **Pygame**

### Other components

- **Player input**

## Connections

- Player input → Pygame: presses keys
- Pygame → Game loop: delivers input
- Game loop → Player: moves
- Game loop → Obstacles: checks collision
- Game loop → Playfield: draws frame
- Player → Playfield: is drawn on
- Obstacles → Playfield: are drawn on
- Game loop → Pygame: updates display
