about angry birds transport

Birds won the fight against bad piggies and all those green creatures are now in prison! Birds are watching them day and night, and have built many prisons to keep their enemies for life. Some of the prisons are full and they need to transport the prisoners to other buildings. Your job is to drive the truck between the prisons securely, because pigs are trying to escape and birds will be very angry. The road is bumpy and the cages can fall down from the truck if you don’t drive carefully. At the end of each transport you will be paid, and each cage worth money. Losing one cage will cost you, and you can lose your job if you lose too many.
