Game gets dull quite quickly, with no real goals or rewards for "good play". Background/racetrack is on a very short loop which doesn't help
I write good play in that manner because there's seemingly no challenge to the game. You accelerate and occasionally wiggle your truck. Fuel is overly plentiful, despite the author comment being that it should be something to be saved
Game may well get more challenging as time goes on, got to 1000km approx. before stopping
Also worth mentioning, the music button mutes the vehicle sounds, while what I assume would be the sound effects button mutes the music. Worth looking into?
