Open-Source Snake Game in WIN32 and jQuery

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.

Snake Definition

The entire snake is a List, with a head squarehead, a direction with four possible values, a speed, and the current snake length List.size().

Collision Detection

When the snake’s head encounters a randomly generated square in the current direction, it means food has been eaten.
When the snake turns back and hits its own body, or hits the boundary, the game is over.
