CppSnake

• This is a simple Snake game written using the ncurses library in C++.

Requirements

• A POSIX-compatible operating system (macOS, FreeBSD, Linux, etc.). Cannot run natively on Windows due to the absence of ncurses library.
• GNU gcc.`
• A terminal emulator with a minimum size of 70x20 (to ensure ASCII arts fit within the terminal's canvas).
• argp.h header file: argp-standalone Homebrew package (macOS) or gnulibc (Linux).
• Developed on macOS 10.14 Mojave.

How to play

• Use WASD to navigate, eat the food to grow up.
• Press Q to quit, P to pause or O to save the game.
• The snake's head cannot overlap the walls nor its body.
• If the terminal window is resized while playing, the game interface will be redrawn to fit the new size.
  If no constant canvas size is specified, the canvas will be the entire terminal, so it will be resized as well.
• Cheat code: / to increase the length by 1 block without having to eat any food. Only present if debug mode is enabled.
