Deep Worm
Worms aren't usually the protagonists of stories, but considering how close they are to snakes, there is room for them to grow. This game is all about a worm's desire to eat and survive despite being hunted by well-equipped creatures. The worm is powerful and fast, but it's not invincible so one needs to use caution. It's just one worm and recovery is not a fast process which is why it needs to use underground to its advantage. It needs to pick the right moments to emerge and reduce its exposure so that humans can't use it for target practice.
