Good day,
I have gone through all your requirements and attachment and found myself very much proficient in developing your game.
I have developed more than 250 games in UNITY 2D/3D games for both Android and iOS, including genres like FPS, third-person shooters, racing simulators including bike, bicycle, and car racing.
Some of them are featured on app store and has million downloads.
Message me so we can take this project towards development.
Many Thanks
AQ.
