Open-Source Snake Game in WIN32 and jQuery

Thu, 03 Sep 2015 15:13:45 +0000

This is a simple snake game available in both WIN32 and JavaScript versions. The WIN32 version was written in 2010 – small but complete. Looking back, I’m quite impressed with myself from over five years ago. The jQuery version was written in 2015.
