Journey back to the Mesozoic with a modern day submarine to study and capture the amazing reptiles that lived in a sea that covered the central part of the United States and bring them back to today. Play the game the way that you want! There is a Learn mode if you just want to find out about these creatures. There is also a Game mode where you can test your skill against these aggressive hunters. We recommend the Learn mode first, so you can "know your enemy." Animals in Game mode have been coded with their biology, so some have better eye sight than others and some swim faster. In Learn mode, the animals are just passively swimming. In Game mode, they will aggressively attack you. Use the sonar screen to track them. There are easy, medium, and hard levels of difficulty in Game mode. There are no ads and no in App purchases. You get the whole game for one low price. This app runs on iPhone 6s+ and later devices or the iPad Pro.

Controls need work

I really like the idea and game, but the controls are weird. I would swap the fire button position with the movement stick and put camera stick like an inch further right.
