Pong in C (open source)

This is game is my version of Pong. It is single player. I wrote it in C using no libraries (not even OpenGL!) You can download the source code to see, learn, play around, make changes, whatever you want. I wanted to make it as simple as I could without using any libraries. It was 528 lines of code (excluding blank lines and comments). I hope you like it. :)
