Less hearts to unlock Dino's and eazyer eggs – Jurassic Island: The Dinosaur Zoo Review

This is a good game but the hearts are a crappy way to unlock things. Developers please change the costs of dinosaurs to unlock! Divide the cost by 2 please. Also make the egg mines get eggs more fast because I've Ben playing yellow for 4 hours and still haven't got eggs. 1 egg per 5 mins please, Thank you.
