If like me you found the first few games hard because you couldn't find the controls well look no further.

-The G button is used for rest stops and gas stops.
-W and S are used to scroll through options
-ENTER is the select button.

On the top right of your game you see your petrol and your awakeness. Pay attention to those.
If your petrol goes to 0 you loose the game.
If you are tired you are likely to crash the car and loose the game.
So sleep when you're tired and fill petrol at any point before it reaches 0.

Enjoy!
