Finished my first game! It's fully complete, with no major bugs that I can find.
Below are downloads for platforms, along with a source tarball that includes its subprojects.
Source Code: Pong-v1.0.tar.xz Pong-v1.0.tar.xz.sha256sum
If you can't run the above, try this build, it uses OpenGL 2.1: pong-v1.0.1-amd64.exe
