# Snake Eater
A snake game written in Python using the Pygame library.
# Snake Eater (Remix)

This is a remix of a snake game written in Python by [rajatdiptabiswas](https://github.com/rajatdiptabiswas) using the Pygame library. Two snakes duke it out to see who can get the biggest.


## Installing
Expand All @@ -14,25 +15,10 @@ pip3 install pygame
## Running the application
Download the source code from the repository and run the file just as any other Python script (.py) file.
```
python3 Snake\ Game.py
python3 Snake\ Game.py <difficulty>
```

The `difficulty` variable can be changed with the values provided in the comment to set the difficulty level.

The rest of the code is properly commented and self explanatory. Tweaks can be made to change the play style or visuals of the game.

*Game over screen*

`<difficulty>` is a parameter that changes the tick rate of the game. If you have a higher difficulty, the tick rate increases, and consequently the snakes get faster, which makes the game more difficult.
