Cool concept that poots a KRANKEN good spin on the Hungry Eveolution games. I like the challenge that getting the interesting food often meant dodging the fish swimming in way.
Two things that I would've liked to see in the game:
An "Endless Mode" message after levelling to 10, just to let me know that I've basically finished the game, and now it's about high score.
And maybe some punishment for attempting to eat a creature I'm not big enough to eat, and maybe also let hunger ticket down as time goes to make a sense of urgency.
