How to translate this concept to Unity code?

Greetings, all!

I'm using Unity 5.2.1f1 for PC. I seek help translating this game concept to code in Unity. I am open to using scripts in any supported language, though I'd prefer to use the same language for all scripts, and the language best suited to the scope of this project if there is one.

Game Platform: Mobile and Tablet

-=GAME CONCEPT=-
A ship automatically moves from left to right across a scrolling background. The ship's elevation changes based on the angle the device is tilted; tilt the device up toward you to move the ship up and tilt the device down away from you to move the ship down. At certain points, the player must rotate the device 180 degrees to cause the ship to turn around - like a U-turn.

-=HOW TO CODE THIS IN UNITY?=-
As I am generally new to working in Unity, what is the best way to do this?

 

Hi,

Good solution would be to start from here,

Or do you have other parts of the game done, except gyro controls?
