My suggestion is to have a button on the screen that will auto orientate you to the direction you are traveling. This will make it easier to get your bearing when playing.
Also, I would like to sugeeest that smaller towns have more drops and dinosaurs. If you have people playing in big cities (millions) who have access to more variety dinosaurs and more drops competing with those in small towns where things are less frequent, those not living in big cities won’t be able to compete and you user base will quickly decline for the rural players. It needs to be consistent per square mileage or road distance or something.
