The truck seems to be very heavy, making it impossible to try and drive over the hills. Despite attempting many tricks with the brakes and acceleration, I only managed to get past the first two hills in level one. Sometimes the car kept on falling flat on its bumper while attempting to drive on the hill. Eventually the driver's expression became the accurate representation of how I felt after many of my attempts to get past the first level.

Kind of boring and the third level is kind of a large leap between the previous ones. that and the truck seems to be off balance.

Too basic and only 7 levels
The car's front more heavy than behind's ?

Its ok but actully boring and too difficult.
