Nice game~ Really love the fish's swimming animation!!
Nicely balanced - after dying several times I worked out the best way to attack each type of fish.
Constructive feedback - It might be nice to have a 'safe area' where you start, as I got bombarded by squid ink straight away on one of my turns :D Also speeding up a little when your health is higher could be a good addition, as it would make eating seem extra profitable, and losing health even more debilitating!
