Slither (Dmitry Krapivin)

This is a logic game with 4 levels (level 0-3). This walkthrough stops when the game loops to level 0 again. The game is made by Dmitry Krapivin and is a remake of a program that appeared in 1985 for the 8-bit Atari, which was originally released as a type-in listing in an issue of ANALOG Computing.
