Honestly, the snakes being made up of words was really, really cute. It's hard to give personality to a terminal game, so 10/10 on that part!
I know this is crazy, but hear me out. What if the snakes could combine themselves into spelling new words, and if they spelled something recognizable they became a more powerful snake? What if the player could? You don't really have that level of control over spelling as it is, but.
