I think that there should be about 1-3 guys should follow u around like bodyguards. But they are a bit weak and you can't upgrade them. It would help with later levels, also they only give 2-5 health points.
I think you should be able to unlock different dinos after going over them or by getting the super eggs, so there can be a bit more fun to the game. also there should be different challenges that are suited for that dino, and you should be able to switch dinos on the menu
