You've started a new dream job - Frog Delivery Person for Froglivery Inc. Your objective is to deliver packages throughout the city in the best possible time and try not to get squashed by traffic or to fall off a building.
To optimise delivery times, your highway is roof and vehicle tops - city streets are just too crowded for a funky frog like you (not to mention people like to eat your legs).
The direction you must go to deliver your package is shown on the game screen. Follow the arrow as best you can and get all your parcels to their destinations within the limited time you have.
Good luck Mr Frog, the fate of Froglivery Inc. rests squarely in your hands and feet.
