Ugui Realized variable speed joystick

Last year just finished Ugui, want to be a snake games ~
The result, of course, is that, like most program apes, the core operating logic is implemented, and the rest is behind.
But yesterday on the Internet to see the same as I this demo post, I snake snake Head is also copied, this really can not endure, or the original put out good ~

--- point here ---

So simple Chinese + Pinyin programming style I'm afraid I have the nerve to use.
