snakesss 0.1.2

//! # Simple 2-player snake game
//!
//! ## Movement
//! - Red player: _arrow keys_
//! - Blue player: _WASD keys_
//!
//! Every melon consumed lengthens the snake.
//! - How to win: **Avoid losing!**
//! - How to lose: **Hit the enemy snake**!
//! - How to make peace: **Frontal collision with the other snake** (ain't
//!   these snakes peculiar creatures...)
//!
//! General strategy:
//!  - _The bigger your snake becomes, the higher the chance your opponent will
//!  not be able to avoid your elooongated snake body._
//!
//! ## About
//! This was done as an educational challenge as a one-day *hackathon*.
//! After watching this [video](https://www.youtube.com/watch?v=HCwMb0KslX8),
//! which sets up the coding ground for the basic snake game.
//!
//! I wish I had more time to implement multiple gamestates (like *MainMenu,
//! ScoreScree...*), but it is what it is.
//!
//! Enjoy!
//!
