Snake Game

Snake game is an Arcade Maze Game which has been developed by Gremlin

Industries. The player’s objective in the game is to achieve maximum points

as possible by collecting food or fruits. The player loses once the snake hits

the wall or hits itself.

## Setup instructions

In order to run this script, You just need the following 3 modules -

- **Pygame:** It is a set of Python modules designed for writing video

games.

- **Time:** This function is used to count the number of seconds elapsed

since the epoch.

- **Random:** This function is used to generate random numbers in Python

by using random module. **Pygame, Time and Random**
