To make the game more challenging we could have it so instead of having tranquilizer darts like we have we could have 2 or 3 different types with different measurements because something able to take out a T rex is used on a compsognathus as well in this game and realistically would kill the creature if the same amount of tranquilizer was used on it, we can use the lower amounts to tranquilize smaller dinosaurs and calm down larger ones to prevent them from escaping while for example, the jeep trying to fix the fence.
The medium Shot of tranquilizer can be used to knock out medium-sized dinosaurs, slow down the larger ones and if used on small dinosaurs can kill.
And then the Larger shot of tranquilizer can be used to knock out the larger dinosaurs and will kill any other medium / small dinosaur.
This would improve the game because all we have to do is shoot a lot of times and the dinosaur is down but if we make it so we have to use the right amount of tranquilizer then it will make it more of a challenge and it will also give you the ability to go full lethal if you want to
