I got my 4th grade class to play gorilla, which interestingly came with the Windows NT machines at my school. That and that reskinned Full Tilt! Pinball table Space Cadet. Quite a contrast. I personally liked modifying nibbles, for instance adjusting the timing loop so it'd be playable on a modern computer. On some occasions I made a special key which would put the snake on auto-pilot (just towards the goal, no graph search or anything), or which would temporarily turn off collision detection. Somehow both of these were possible without really understanding how the whole program worked.
