Mining Truck 2 - Trolley Transport Hacked

Your task in this cool physics skill game is to deliver as much freight as possible to the end of each level. Try not to loose any items on your way. Does delivering goods from point A to point B sounds easy and boring to you? What if the goods have to be delivered on a small trolley, moving through a complex system of underground mining tunnels? I guess it gets more interesting now. You can also use earned money to upgrade your mining truck and deliver even more cargo.
