Stringlink, a game by Sasakoge is actually a spiced up version of the classic Snake game.

Apart from the traditional twists and turns you have to make on your never stopping snake, there are also stuff like:
– Limited number of turns that can be increased if you change the color of your snake;
– You can change the color of your snake by making a turn while on a colored block;
– Along the playing area you’ll find several colored “walls” which you can break, provided they are not the same color as your snake.
With those in mind, get the freeware Stringlink on the official download website or at the Stringlink mirror page.
Also, for those who don’t know how to use a .lzh file, source IndieGames has the instructions.
