MilkSnake is a new take on the classical snake game. It is played on the surface of a torus rather than on a flat plane.
It requires a decent graphics card! It will run on weaker hardware, such as the Intel GMA chipsets found in many MacBooks, but the graphics quality will be lower.
There are several different difficulty levels, so it can be enjoyed by both inexperienced players as well as those looking for a challenge. You can also share your scores online on Twitter, or anywhere you can post links.
