The object of the game depends on the selected adventure*
The game itself already offers four adventures:
A simple race to get you accustomed to the game mechanism
Bumble Bee Run
A tricky scenario where you need some good flying abilities
Chasing The Cat
A wild turmoil where you are allowed to execute some fine ram attacks
A fast chase where you, the hunter, ... might get hunted
The first adventure introduces you to the basic rules.
Each further adventure introduces an new advanced rule.
