Well sorta? I wasn't really playing to the spirit of the game. Maybe if the snake got slightly faster as it grew, but I was intentionally having a bit of fun with it. When I played it properly there was a lot to do. Possibly if you limited the number of blocks you can place or have them disappear after a set bit of time. (IDK if you've seen the carrots in ocarina of time, limited to five but they regenerate constantly)
