A simple Tic Tac Toe game written in C using the Raylib graphics library.
Should work on Linux, Macs, Windows, and possibly even more.
Just download ttc.c, link it to <raylib.h>, compile it, and run.
Using GCC on Unix-like:
$ gcc -o game -lraylib ttc.c
$ chmod +x game
$ ./game
Go check Raylib's documentation to see how to install it on your OS, and check your OS's documentation to find out how to compile the program.
