The player is a Monkfish in the deep waters of the Pacific Ocean. They will view the world from a top down perspective and navigate in 2 dimensions through the dark and murky void.

The player collects glowing food particles which he uses as power (power level is indicated by how much you glow. Glow also affects your radius of sight) to generate small food particles near other helpless fish. These fed fish are then deceived to follow you, acting as a shield against the hostile environment.

Mainly there are simply aggressive creatures that will stalk the player and eat one of the followers and eventually eat you if you are left alone. There is also the deceptive angler fish who will lure the player with an appendage that mimics a glowing food particle and then could strike and eat you if you get too close.
