Very introspective, but I feel that after the seagull and jellyfish chapters that you lost heart. You didn't get into the beast's mind like you did with the first two.
A shark's hatred for a dolphin's terrible nose that always stabbed them in the gills?
Or the mind of the vortex drone and the utter and total devotion to their mother?
Making Ecco see how everything, from the fish he devour from the vortex themselves are just doing what they believe they have to, to survive.
