Spiked is a MacOS Classic 2-player arcade game which was released in 1997. It does not run on recent versions of MacOS X without significant contortions.
I started writing Spiked when I was in high school, and finished it in college. Many years later, when I was cleaning up an old server, I found the source code in a corner gathering dust, and figured it would be nice to post it before it got lost. Do not judge me on the code quality; it was half a lifetime ago. That being said, I'm fairly impressed that the Past Me pulled this off.
See the about.txt file for more information on gameplay.
I had originally released Spiked as "freeware," not quite knowing that there was a whole open-source thing going on. While I still want to stay true to that intent, I've revised the license to be under the GPL-3.0; see the gpl-3.0.txt file.
