UI / Interface / food
I am missing customizing so that you can move HP bar/energy/breath(underwater) from bottom to the top etc. via UI/interface or around the screen to fit your playstyle or change the size.
Maybe an extra zoom out to be able to see more of my dino.
And im also missing a little party overview (like in wow/mmorpgs) where you can see who you are in a party with and their HP etc. on the left side of the page.
Maybe more fish in the water or fruits or critters.. to make the game more alive.. and help to find food.
