I'd have almost argued that this game went under the 'anti-lens' of every life counts, if going under the lens of "snake eats lives". Then again, it could ironically be implemented under not only the lens of 'if the fox eats all the chickens and eggs. They'd be no lives left to feed from'. Along with the objective giving the 'twist' ending of having to strangle/circle around a chicken.
So, tangibly wise. The twist, makes it nicely related to the game jam theme, for a 'simple' snake game. :)
