Player 1 W~~Up A~~Left S~~Down D~~Right You play as Jorunna, a small sea slug trying to avoid being eaten by Navanax. Player 2 /\ ~~Up >~~Right V~~Down <~~Left You play as a large predatory sea slug named Navanax, your goal is to eat Jorunna before the time runs out.
The background is Scratch, the sea slugs are real pictures of sea slugs (Jorunna and Navanax are their real scientific names). Only other people as nerdy as me are going to understand this, but I hope other people can still enjoy it. I got the idea for this from my favorite BBC narrator, David Attenborough! (The scene where Navanax is chasing Janulis in the Seasonal Seas Documentary... see i am a nerd).
