Deliver the cargo loaded on the truck to the destination. To get to your destination, you need to be prudent, because if you drive at random, you will run out of fuel.
We can say that each level is a mission, and the fuel tank is a timer that you need to worry about, and if you use up all the fuel before reaching the goal, then the level will fail.
on PC: WASD - truck movement, Space bar - handbrake.
on a mobile device: touch on game elements on the touch screen.
