The game feel in this is great, it's very well put together. I think there should be some sound effect when another animal eats, probably a different one from the player's; when I first saw eaten remains out of the corner of my eye, I thought they were being destroyed by a bug. The Plesiosaurus made a good tricky boss. I thought it would be really easy, but the long neck made it harder to avoid retaliation when going in for a strike. Great game!
