This is interesting and is has been nice to see it evolve (pun intended).
A little feedback:
As a level 1, I can spawn and be surrounded by multiple higher level dinosaurs so perhaps a little easing in to initially start.
As a level 1 I don't appear to have any advantages to a higher level. I am not faster or more agile, I'm just edible. I would be nice to have some trait to assist in surviving -being a little quicker, being able to turn more quickly or even the ability to hide/not be detected if I am not moving.
It does look absolutely and sound fantastic!
