Terminal Snake Game in C++

Features

• Modular OOP Architecture: Divided into highly encapsulated classes (Snake, Food, Board, GameManager).
• Cross-Platform Input System: Custom macOS terminal handling using raw input mode, supporting both standard WASD and Arrow Keys (ANSI escape sequences).
• Flicker-Free Rendering: Redraws the board on the fly by resetting the terminal cursor to the top-left rather than clearing the whole screen.
• Score & Level Mechanics: Tracks player score and increases speed as you eat more food.
• Collision Detection: Full wall-boundary and self-collision checks.

Project Structure

• run.cpp - The entry point containing the main() function.
• game_manager.h / game_manager.cpp - Manages the main game loop, level difficulty, updates, and input processing.
• snake_class.h / snake_class.cpp - Manages the snake's body coordinates (using std::deque), movement direction, growth, and self-collision.
• board_class.h / board_class.cpp - Coordinates grid rendering (Draw) and handles wall boundary collisions.
• food_class.h / food_class.cpp - Uses modern C++ random number generation to spawn food at random coordinates not occupied by the snake.
• terminal.h / terminal.cpp - Configures the terminal to raw/non-blocking mode using the POSIX termios API.
