Haskell Snake (And not only Snake) Game

A simple Snake game implemented in Haskell using the Brick library for terminal-based UI. And as a bonus - Tetris!

Overview

This project is a classic Snake game where the player controls a snake that moves around the screen, eating food to grow longer while avoiding collisions with itself. The game features:

• Terminal-based graphics using the Brick library
• Arrow key controls for snake movement
• Random food placement
• Collision detection
• Wrapping around screen edges

Because implementing Snake was so much fun, I decided to add Tetris as well! After all, programming shouldn't be about "endomorphic pseudofunctors" but about writing code that makes us feel happy and productive.

How to Play

Snake

• Use arrow keys to change the snake's direction
• Eat food (marked as 'o') to grow longer
• Avoid colliding with your own tail
• Press 'q' or Esc to quit the game

Tetris

• Use arrow keys to move and rotate pieces
• Press 'q' or Esc to quit the game

Implementation Details

The game is built with a clear separation of concerns:

• Game.Core: Core game logic and state management
• Game.UI: User interface and event handling

This project was developed as a recreational activity and as a Test-Driven Development (TDD) exercise, with comprehensive test cases ensuring the game logic works as expected.

And readme was generated by Claude.

Run the game

By default, the game runs Snake:

cabal run

You can explicitly choose which game to run:

cabal run -- snake    # Run Snake game
cabal run -- tetris   # Run Tetris game

Run the tests

cabal test
