Honestly I wouldn't have cared about the unkillable fish until they added fish that shoot needles at you and other fish that dart at you as soon as you get out the tadpole and other fish that shocks you with electricity so with all that to consider I believe we should have something to defend ourselves. And other than that the game is great besides how short the story part is because it took how long to make this first part of the game and yet I've already completed everything in the game in 2 days like come on.
