To run this game, run the following commands:

sudo apt update
sudo apt install cmake
sudo apt install build-essential
sudo apt install libsfml-dev
mkdir build
cd build
cmake ..
make # (use “sudo apt install make” if not already installed on your system)

Now open the build folder — you'll find an executable file named xonix.

./xonix
